摘要:
Liquid crystal display (LCD) has sub-pixel domains in each of pixels to obtain a wide viewing angle. The sub-pixel domains are formed by divided orientation alignment in which the sub-pixel domain are subjected to rubbing in different directions opposite to each other. The liquid crystal has a splay-type TN deformation structure in the first sub-pixel domain and a normal TN deformation structure in the second sub-pixel domain. The pre-tilt angles of the liquid crystal in the first domain and second domain are selected to obtain a wide viewing angle. The LCD has a shield pattern for shielding disclination causing afterimages and storage capacitor electrodes having a function as signal lines.

A liquid crystal display having a wide viewing angle and easily manufactured. The liquid crystal display comprises an upper substrate and a lower substrate, and a liquid crystal material disposed between the upper substrate and the lower substrate. The liquid crystal display has a conductive protrusion disposed on the surface of the upper substrate opposing to the lower substrate. The conductive protrusion is disposed over a scanning electrode line or a signal electrode line and has the same potential as that of the upper electrode. As another structure, each of pixel electrodes on the lower substrate has a smaller area than that of a common electrode on the upper substrate and is covered by the common electrode, and each of the pixel electrodes comprises an electrode portion having approximately symmetrical shape.

A pattern formation method includes the steps of forming a flowable film made of a material with flowability; forming at least one of a concave portion and a convex portion provided on a pressing face of a pressing member onto the flowable film by pressing the pressing member against the flowable film; forming a solidified film by solidifying the flowable film, onto which the at least one of a concave portion and a convex portion has been transferred, through annealing at a first temperature with the pressing member pressed against the flowable film; and forming a pattern made of the solidified film burnt by annealing at a second temperature higher than the first temperature.
摘要:
An active matrix liquid crystal display panel by which a good display characteristic can be obtained without suffering from gradation reversal over a wide visibility angle range. A liquid crystal layer 4 is formed such that the thickness-thereof varies in accordance with transmission wavelengths of color layers 6, 7 and 8 so that a very good display which does not exhibit any coloring in whichever direction it is viewed may be obtained. An active matrix substrate A includes a plurality of opposing electrodes 2, a plurality of pixel electrodes 3 parallel to the opposing electrodes 2, a thin film transistor, and an orientation film 23 all formed on a glass substrate 10. A color filter substrate C includes an orientation film 56 provided on one surface of another glass substrate 10 and an optical compensation layer 35 provided on the other surface of the glass substrate 10 and formed from a plastic film. The two substrates are disposed such that the orientation films thereof oppose each other, and polarization plates 34 and 5 are disposed on the outer sides of the two substrates, and a liquid crystal layer 4 having a positive refractive index anisotropy is provided between the orientation films 23. The optical compensation layer 35 has a negative one axial refractive index anisotropy and can cancel a retardation produced in the liquid crystal layer 4 thereby to suppress white floating of a black display portion.
摘要:
An in-plane-switching liquid crystal display unit has a two-dimensional matrix of pixel regions each including a first auxiliary region and a second auxiliary region. When no electric field is applied, liquid crystal molecules in the first and second auxiliary regions are directed in respective orientations that lie at 90° with respect to each other. When a voltage is applied, the liquid crystal molecules are rotated in the same direction while maintaining their orientations in the first and second auxiliary regions at 90° with respect to each other. Alternatively, the liquid crystal molecules in the first and second auxiliary regions are directed in the same orientation when no electric field is applied, and when a voltage is applied, the liquid crystal molecules are rotated opposite directions while maintaining their orientations in symmetric relationship.
