摘要:
On a TFT substrate, a TFT using a low-temperature poly silicon thin film as an active layer is formed and a plurality of pixel electrodes are formed over the TFT and its electrode wiring, with an interlayer insulating layer between. In a common electrode formed on an opposite substrate opposite the TFT substrate with a liquid crystal layer between, an alignment controlling window for the liquid crystal is formed at a predetermined position opposite each of the pixel electrodes. A wide viewing angle is achieved by dividing an alignment area of liquid crystal molecules in one pixel area. The liquid crystal layer is vertically aligned and can be operated at a low driving voltage obtained by a poly silicon TFT by including fluorine liquid crystal molecules having negative dielectric anisotropy and fluorine side chains in the liquid crystal.

A vertically aligned type liquid crystal display includes a liquid crystal layer disposed between a plurality of pixel electrodes and a common electrode and containing vertically aligned liquid crystal molecules, the orientation of the liquid crystal molecules being controlled by electric field. An orientation control window is formed in the common electrode. A distance Wp between adjacent pixel electrodes and/or a width Ws of the orientation control window is selected so as to satisfy Wp≧d/2 and/or Ws≧d/2, where d is a distance (or a cell gap) between the pixel electrodes and the common electrode. Viewing angle is widened and a viewing angle characteristic is improved, and abnormal orientation or grittiness of an image is eliminated.

摘要:
On a substrate, a gate electrode, a gate insulating film covering the gate electrode, a p-Si film, and an interlayer insulating film covering the p-Si film are formed. On these a drain electrode and a source electrode are formed, so as to form a thin film transistor. In addition, a smoothing insulator film covering the thin film transistor, a pixel electrode, and a vertical alignment film covering the pixel electrode are formed. The vertical alignment film is not processed with rubbing treatment, so that the liquid crystal having negative dielectric constant anisotropy is controlled in an initial direction of the substantially normal direction without pretilt. Upon applying a voltage, the tilt of the orientation is controlled in the direction of a slanting electric field at the edge of the pixel electrode, so that a pixel division is performed. Since the rubbing treatment is not performed, electrostatic breakdown of the thin film transistor is prevented.

A pixel electrode for driving liquid crystal is formed on a planarization insulator film covering a thin film transistor, and a vertical alignment film without rubbing treatment is formed on the pixel electrode. An alignment control window that has electrode-free portion is formed in a common electrode, and a vertical alignment film is formed on the common electrode without rubbing treatment. The liquid crystal having negative dielectric constant anisotropy is controlled in an initial direction of the substantially normal direction without pretilt. Upon applying a voltage, the tilt of the alignment is controlled in the direction of a slanting electric field at the edge of the pixel electrode and the edge of the alignment control window, so that pixel division is performed. Since rubbing treatment is not performed, electrostatic breakdown of the thin film transistor is prevented and, because a black matrix is eliminated, aperture ratio is improved.

摘要:
The invention is directed to the higher contrast in a liquid crystal display device (LCD) having a lighting portion as a front light. A lighting portion is formed by interposing an organic EL layer between a transparent substrate and a transparent substrate. A light shield layer is formed covering a cathode layer of the organic EL element layer. The lighting portion is disposed above the reflective LCD. The reflective LCD has a polarizing plate, a light scattering layer, an opposing substrate, a common electrode, a liquid crystal layer, and a TFT substrate. When the refractive indexes of seven layers of an anode layer, the transparent substrate, a resin layer, the polarizing plate, the light scattering layer, the opposing substrate, and the common electrode are defined as n(1), n(2), n(3), n(4), n(5), n(6), and n(7) respectively, the relation of 1.33>n(k)/n(k+1)>0.75(k=1−6) holds.
摘要:
A heads-up display system includes a liquid crystal display unit that can change optical characteristics in accordance with a video signal. The light modulated by the liquid crystal display unit is projected on a surface of a transparent plate that can reflect the light so as to realize a projection display. The light projected on the transparent plate is polarized light having a transmission axis extending in a direction parallel to a line defining the center with respect to incident light and reflective light of the transparent plate.
摘要:
On a first substrate, a TFT which is a switching element is provided for each pixel, and above an insulating film covering this TFT, a reflective layer which is insulated from the TFT and which reflects light entering a second substrate and transmitting through a second electrode made of ITO is formed. Further, a first electrode having a work function similar to that of the second electrode and made of a transparent conductive material such as ITO is formed closer to a liquid crystal layer than the reflective layer, and this first electrode is connected with the TFT. With this configuration, the liquid crystal layer can be symmetrically AC driven by the first and second electrodes. A reliable connection between the first electrode and the TFT is provided through a connection metal layer made of a refractory metal.
摘要:
A liquid crystal display is disclosed in which a TFT is formed by forming on a substrate (10), a gate electrode (11), a gate insulation film (13), an a-Si layer (14), an etching stopper (15), an (N+a-Si) layer (16), a source electrode (17), and a drain electrode (18) in this sequence. Covering this TFT, an inter-layer insulation film (20) is formed, on which a pixel electrode (22) is then formed. In a common electrode (31), there is formed an orientation control window (32) where no electrodes are situated. With this arrangement, it is possible to prevent the orientation of liquid crystal molecules from being disturbed due to the influence of electric fields generated by the gate electrode (11), the drain electrode (18), or their respective associated lines. As a result, the orientation of liquid crystal molecules is effectively controlled through electric fields generated in the sloped direction around the edges of the pixel electrode (22) and orientation control window (32), thereby obtaining preferable pixel dividing and a wider range of visibility.
