摘要： During a drive period, luminance momentarily decreases when the value β(A−B) is positive and momentarily increases when the value β(A−B) is negative. When the luminance increases during a pause period in accordance with the balance in time constant between an alignment film and a liquid crystal material that are included in a pixel forming portion, primary and secondary parasitic capacitances are adjusted so as to set the value β(A−B) to be negative.

摘要： A first photo-alignment film (12) of a liquid crystal display device (100) includes a first and a second pre-tilt region (12a, 12b) defining pre-tilt directions (PD1, PD2) that are anti-parallel to each other, and a second photo-alignment film (22) thereof includes a third and a fourth pre-tilt region (22a, 22b) defining pre-tilt directions (PD3, PD4) that are anti-parallel to each other. The entire boundary (BD1) between the first and second pre-tilt regions and the entire boundary (BD2) between the third and fourth pre-tilt regions are aligned with each other, as seen from the display plane normal direction. A pixel electrode (11) includes a first and a second cut-off portion (11a1, 11a2) provided by cutting off at least a part of a particular edge portion (11e1, 11e2) of the outer perimeter thereof.

摘要： 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.
