摘要： A liquid crystal display apparatus provided with liquid crystal compensation plates and λ/4 plates on both sides of a liquid crystal cell, in a sequence that the liquid crystal compensation plates, then the λ/4 plates. Further provided is Rth compensation film between the λ/4 plate and linear polarization film. Set substantially at zero is a retardation Rth1 in a perpendicular direction in a range from the linear polarization films to the λ/4 plates, excluding the λ/4 plates. This gives a retardation (in a perpendicular direction) for optically compensating the liquid crystal cell a closer position to the liquid crystal cell. As a result, a broad angle of visibility can be maintained, without losing a balance between viewing angle characteristics from the above position (or the bottom position) and those from the right position (or the left position), while it is possible to prevent contrast ratio in a front direction from being lowered. Therefore, an LCD having good display quality can be realized.

摘要： A liquid crystal display device of the present invention has an arrangement wherein between (a) a liquid crystal display element prepared by inserting a liquid crystal layer to a spacing between a pair of electrode substrates and (b) a pair of polarizers provided on the both sides of the liquid crystal display element, there is provided at least one phase difference plate having a negative refractive index anisotropy whose optical axis is inclined with respect to a direction normal to the surface thereof, and a change, with a wavelength of light, in the refractive index anisotropy of a liquid crystal material constituting the liquid crystal layer is set in a range which does not generate viewing-angle-dependant coloration on a liquid crystal screen.
