Abstract: 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.

Abstract: 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 90null 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 90null 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.

Abstract: A signal correcting circuit, which adds a correction value generated based on a signal stored in a frame memory to an input signal and outputs a resultant signal, is used to correct image data which is an input signal to a liquid crystal display to thereby completely compensate for the influence of the asymmetry of the input signal on the liquid crystal display. This prevents generation of residual images and flickering of the screen.

Abstract: An in-plane switching mode active matrix type liquid crystal display device includes a first substrate, a second substrate located opposing the first substrate, and a liquid crystal layer sandwiched between the first and second substrates. The first substrate includes a thin film transistor, a pixel electrode each associated to a pixel to be driven, a common electrode to which a reference voltage is applied, data lines, a scanning line, and common electrode lines. Molecular axes of liquid crystal are rotated in a plane parallel with the first substrate by an electric field substantially parallel with a plane of the first substrate to thereby display certain images. The common electrode is composed of transparent material, and are formed on a layer located closer to the liquid crystal layer than the data lines. The common electrode entirely overlaps the data lines except an area where the data lines are located in the vicinity of the scanning line. The liquid crystal display device further includes a light-impermeable layer in an area where the common electrode entirely overlaps the data lines. The light-impermeable layer is comprised of a black matrix layer having a width smaller than a width of the common electrode.
