Patent ID: 8319923

Claim:
A liquid crystal display device comprising: first and second polarizing plates which are arranged such that respective transmission axes thereof are perpendicular to each other; a liquid crystal cell which is arranged between the first and second polarizing plates; a first viewing angle compensating film which is arranged between the first polarizing plate and the liquid crystal cell, and comprises discotic liquid crystal molecules; a second viewing angle compensating film which is arranged between the second polarizing plate and the liquid crystal cell, and comprises discotic liquid crystal molecules; a first retardation plate arranged between the first polarizing plate and the first viewing angle compensating film; and a second retardation plate arranged between the second polarizing plate and the second viewing angle compensating film; wherein the liquid crystal cell comprises: a first substrate having at least one first electrode; a second substrate having at least one second electrode; and a liquid crystal layer which includes liquid crystal molecules having a positive dielectric anisotropy, is provided between the first and second electrodes, and is in a homogeneous state when an electric field is not applied between the first and second electrodes; wherein the liquid crystal layer is set such that, when in the homogeneous state, the liquid crystal molecules are twist-aligned at a twist angle of substantially 90°, from a first molecular aligning direction on a side of the first substrate toward a second molecular aligning direction on a side of the second substrate; wherein the first polarizing plate is arranged such that a transmission axis thereof is set to substantially 45° with respect to the first molecular aligning direction and a delaying axis of the first retardation plate, and wherein the second polarizing plate is arranged such that a transmission axis thereof is set to substantially 45° with respect to the second molecular aligning direction and a delaying axis of the second retardation plate.
