According to one embodiment of the present invention, the VA-LCD having liquid crystal cells in which liquid crystals with a negative dielectric anisotropy are filled and which is provided between a first polarizer and a second polarizer, whose absorption axises are perpendicular to each other, includes a sheet of +A plate and a sheet of -C plate, disposed between the first polarizer and the liquid crystal cells; and a sheet of +A plate disposed between the second polarizer and the liquid crystal cells, wherein an optical axis of the +A plate near the first polarizer is perpendicular to the absorption axis of the first polarizer, and an optical axis of the +A plate near the second polarizer is perpendicular to the absorption axis of the second polarizer. According to another embodiment of the present invention, a VA-LCD having liquid crystal cells in which liquid crystals with a negative dielectric anisotropy are filled and which are disposed between a first polarizer and a second polarizer, whose absorption axises are perpendicular to each other, includes a bi-axial retardation film disposed between the first polarizer and the liquid crystal cells, and a sheet of +A plate disposed between the second polarizer and the liquid crystal cells, wherein an optical axis of the bi-axial retardation film near the first polarizer is perpendicular to the absorption axis of the first polarizer, and an optical axis of the +A plate is parallel with the absorption axis of the second polarizer. Accordingly, the configuration of FlG. 11 has not an advantage more than the configurations of F1G.2 and 3 in aspects of manufacturing process and cost. The VA-LCD according to the present invention has an advantage that viewing angle compensation effect is enhanced due to the arrangement of the viewing angle compensation films, thereby implementing the wider viewing angle characteristic.

摘要： An IPS-LCD, in which the direction of an optical axis and retardation values are adjusted according to the disposition of a phase retardation film replacing one protective film, obtains a contrast ratio similar to that of an IPS-LCD having upper and lower protective films, and has a small thickness. The IPS-LCD includes first and second polarizing plates (1, 2), an IPS panel (3), and a first protective film. Absorption axes (4, 5) of the first and second polarizing plates (1, 2) are orthogonal to each other, and an optical axis of a liquid crystal in the IPS panel (3) and the absorption axis (4) are parallel with each other. A second phase retardation film, obtained by coating a biaxial film (17) with a uniaxial C film (11), is disposed between the second polarizing plate (2) and the IPS panel (3) and is used as a second protective film.
