Abstract:
A vertical alignment liquid crystal panel based on a transverse electric field drive system is provided which shows few changes in color when looked squarely at. A liquid crystal panel (2) is a vertical alignment liquid crystal panel based on a transverse electric field drive system, which carries out a display by driving, with a transverse electric field, a liquid crystal layer (50) sandwiched between substrates (10, 20), and the substrate (10) is provided with an insulating layer (25) having at least two regions that are different in relative permittivity from each other in a pixel (6) composed of a red subpixel (6R), a green subpixel (6G), and a blue subpixel (6B). Those regions of the insulating layer (25) which correspond to the blue, green, and red subpixel (6B, 6G, 6R) in the liquid crystal panel (2) have relative permittivities of 3, 3 to 7, and 4 to 7, respectively.
