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.
