Liquid crystal panel, liquid crystal display unit, liquid crystal display device, and television receiver
Abstract:
A liquid crystal panel includes: an active matrix substrate (3) including a transparent substrate (31) formed with a transistor, a pixel electrode, and a signal wire; a color filter substrate (30) including a transparent substrate (32) formed with a common electrode; a liquid crystal material (40) disposed between the substrates (3, 30); and a spherical main spacer (2m) contacting the active matrix substrate (3) and the color filter substrate (30). The active matrix substrate (3) has a surface including a sub spacer region (SA) away from the transparent substrate (31) at a distance shorter than a distance between the transparent substrate and a portion where the surface of the active matrix substrate (3) contacts the main spacer (2m). A spherical sub spacer (2s) is disposed to overlap the sub spacer region (SA). This provides a liquid crystal panel where liquid crystal bubbles hardly occur even when the liquid crystal material contracts due to low temperature, etc.
