Abstract: 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.

Abstract: The TFT substrate (10) of this liquid crystal display device (100) includes: a TFT (11) which is provided for each pixel; an upper electrode (12) which is electrically connected to the TFT's drain electrode (11d); a lower electrode (13) which is arranged under the upper electrode; and a dielectric layer (14) which is arranged between the upper and lower electrodes. Its counter substrate (20) includes a counter electrode (21) which faces the upper electrode. The upper electrode has first and second regions (R1, R2) which have mutually different electrode structures, and a third region (R3) which electrically connects the first and second regions to the drain electrode. The third region of the upper electrode includes a symmetrical connecting portion (12c) that is a conductive film pattern, of which the shape is substantially symmetrical with respect to a virtual line (L1) that splits each pixel into two adjacent regions in a row direction.
