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.

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 region. When no electric field is applied, liquid crystal molecules in the first and second 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 regions at 90° with respect to each other. Alternatively, the liquid crystal molecules in the first and second 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.

There is provided an in-plane switching type liquid crystal display including (a) first and second polarizing plates facing each other and spaced away from each other, (b) a liquid crystal layer situated between the first and second polarizing plates, orientation azimuth of the liquid crystal layer being caused to vary by an electric field parallel to a substrate, (c) a first compensation layer situated between the first and second polarizing plates, the first compensation layer having positive uniaxial, optical anisotropy, and having an optical axis extending perpendicularly to the substrate, the first compensation layer varying birefringence thereof to thereby compensate for fluctuation in birefringence of the liquid crystal layer, caused by variation of a viewing angle, and (d) a second compensation layer situated between the first and second polarizing plates, the second compensation layer having positive uniaxial, optical anisotropy, and having an optical axis extending in parallel with the substrate and perpendicularly to initial orientation of the liquid crystal layer. Since a variation in birefringence of the first compensation layer cancels a variation in birefringence of the liquid crystal layer, the in-plane switching type liquid crystal display provides qualified images with less color caused by a change in a viewing angle.
