Abstract:
A liquid crystal display device (100) includes a liquid crystal layer (30) of a vertical alignment type, a first photo-alignment film (12), and a second photo-alignment film (22). The first photo-alignment film includes a first pre-tilt region (12a) and a second pre-tilt region (12b) defining pre-tilt directions (PD1, PD2) that are anti-parallel to each other. The second photo-alignment film includes a third pre-tilt region (22a) and a fourth pre-tilt region (22b) defining pre-tilt directions (PD3, PD4) that are anti-parallel to each other. The entire boundary (BD1) between the first pre-tilt region and the second pre-tilt region and the entire boundary (BD2) between the third pre-tilt region and the fourth pre-tilt region are aligned with each other, as seen from the display plane normal direction.
