    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.

  • Patent number: 8704860
    Abstract: An overshooting process is carried out, in an LCD device (1) whose LC layer thicknesses meet pixel R>pixel G>pixel B, so as to respectively set first through third output gray scales of current frame based on (i) first through third input gray scales of the current frame (current frame data) and (ii) first through third gray scales of frame which is one frame before the current frame (previous frame data). The first through third output gray scales are respectively set for the first through third pixels based on the thicknesses of the respective first through third liquid crystal layers so as to meet pixel R>pixel G>pixel B. This equalizes liquid crystal response speeds of the respective pixels R, G, and B, and therefore allows an improvement in display quality of the LCD device (1) having a multi gap structure.
