Embodiment 1
[0114]
[0115] Such as figure 1 As shown in , the electrodes are arranged on a glass substrate with an interval of 20 μm between adjacent electrodes ( figure 1 2 and 3) in , on which a polyimide film as an alignment film was provided and subjected to rubbing treatment. exist figure 1 Perform rubbing in direction 4 as shown in . On one surface of a piece of glass substrate, a polyimide film, which was separately prepared and rubbed, was provided, thereby forming an alignment film. Two glass substrates were stacked and laminated to each other in such a manner that the alignment films faced each other, the gap (d) between the substrates was adjusted to 3.9 μm, and the rubbing directions of the two glass substrates were parallel. Next, a nematic liquid crystal composition having a refractive index anisotropy (Δn) of 0.0769 and a positive dielectric anisotropy (Δε) of 4.5 was charged therein. The liquid crystal layer had a value of d·Δn of 300 nm.

Embodiment 2
[0187] The prepared first retardation region No. 2 was pasted to the polarizing plate protective film No. 1 side of polarizing plate B using an acrylic adhesive in the following manner, that is, the transmission axis of the polarizing film and the slow axis of the first retardation region No. 2 perpendicular to each other. Furthermore, the second retardation region No. 1 was pasted thereon using an acrylic adhesive.
[0188] This laminate was pasted on one side of the previously prepared IPS mode liquid crystal cell No. 1 in such a manner that the transmission axis of the polarizing plate was parallel to the rubbing direction of the liquid crystal cell (that is to say, in the black state, the first retardation region The slow axis of No. 2 perpendicularly crosses the slow axis of the liquid crystal molecules of the liquid crystal cell) and the No. 1 side of the second retardation region faces the liquid crystal cell side.
[0189] Subsequently, the polarizing plate B was past...
Embodiment 3
[0191] The prepared first retardation region No. 3 was attached to the polarizing plate D using an acrylic adhesive in such a manner that the transmission axis of the polarizing film and the slow axis of the first retardation region No. 3 were parallel to each other. In this configuration, FUJITAC TD80UF having 2 nm Re and 48 nm Rth as the protective film of the polarizing plate D corresponds to the second retardation region.
[0192] This laminate was pasted on one side of the previously prepared IPS mode liquid crystal cell No. 1 in such a manner that the transmission axis of the polarizing plate was parallel to the rubbing direction of the liquid crystal cell (that is to say, in the black state, the first retardation region The slow axis of No. 3 is parallel to the slow axis of the liquid crystal molecules of the liquid crystal cell) and the No. 3 side of the first retardation region faces the liquid crystal cell side.
[0193] Subsequently, polarizing plate C was pasted on...
