Abstract: This liquid crystal display device (100) includes: a vertical alignment liquid crystal layer (30); first and second substrates (10, 20); first and second electrodes (11, 21) arranged on the first and second substrates to face the liquid crystal layer; and two photo-alignment films (12, 22). Each pixel region includes first and second liquid crystal domains, of which the reference alignment directions defined by the two photo-alignment films are a first direction and a second direction different from the first direction, respectively. The first electrode has a slit cut region (11R1), through which a slit (11s) has been cut to run substantially parallel to the reference alignment direction, in a part of a region allocated to each of the first and second liquid crystal domains. The width (W) of the slit is set so that when the highest grayscale voltage is applied to the first electrode, an effective applied voltage decreases by at least 0.5 V and the alignment direction of liquid crystal molecules (30a) shifts with respect to the reference alignment direction by less than 45 degrees.
