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 reflective layer for reflecting light incident from a second substrate side and transmitting through a second electrode made of ITO or the like is formed above a first substrate, a switching element provided for each pixel, and an insulating film covering the switching element, the reflective layer being insulated from the switching element. A first electrode having a work function similar to the second electrode and made of a transparent conductive material such as ITO is formed more proximate to a liquid crystal layer than is the reflective layer and is connected to the switching element. The thickness of the first electrode is set to 100 Å or less or in a range approximately from 750 Å to 1250 Å. Alternatively, the switching element maybe connected to the reflective electrode, the first electrode and the reflective electrode which are formed with an insulating film therebetween may be capacitively coupled, and the first electrode may be driven by the reflective electrode via the capacitor.

摘要： An LCD apparatus having a liquid crystal layer sealed between a first substrate having a first electrode and a second substrate having a second electrode, wherein the first substrate comprises a reflective layer formed only in a subregion within a pixel region, for reflecting light. A transparent conductive material is used for the first electrode and the first electrode made of the transparent conductive material is layered to cover a transmissive region within a pixel region and over the reflective layer in a reflective region within the pixel region to directly cover the reflective layer. Optimum cell gaps dr and dt are set in the reflective and the transmissive regions, respectively, based on a twist angle, which is a difference between the alignment directions of liquid crystal at the side of the first electrode and of liquid crystal at the side of the second electrode so that an optimum reflectivity and an optimum transmittance are realized in each region to allow enhancements in the quality of a transflective LCD. A configuration may be employed in which a switching element is formed over the first substrate and the reflective layer is placed in the reflective region of a pixel region on an insulating film which covers the switching element, the reflective layer being insulated from the switching element, the work functions for the first electrode and for the second electrode are similar.

摘要： A vertical alignment liquid crystal layer is sealed between a first substrate having a first electrode and a second substrate having a second electrode, each pixel region has a reflective region and a transmissive region, and a gap adjusting section is provided on one of sides of the first substrate and the second substrate which sets a thickness (gap) d of the liquid crystal layer which controls a phase difference of incident light to the liquid crystal layer so that a gap dr in the reflective region is smaller than a gap dt in the transmissive region. An alignment controller which divides alignment of the liquid crystal within a pixel region is provided in the pixel region on at least one of the sides of the first substrate and the second substrate. It is also possible to optimize by changing the gap in red, green, and blue.
