Abstract
A liquid crystal panel () is a vertical alignment type liquid crystal panel using a horizontal electric field driving system which performs display by driving a liquid crystal layer () interposed between substrates () in a horizontal electric field, each pixel includes three sub-pixels (R,G, andB), which are of red, green, and blue, comb-shaped electrodes () include a function as a diffraction grating with the comb-shaped electrodes () and spaces between the comb-shaped electrodes (), and pitch distances (D) between electrodes are set such that an optical diffraction efficiency for red wavelength and an optical diffraction efficiency for green wavelength are greater than an optical diffraction efficiency for blue wavelength. Thus, it is possible to provide a liquid crystal panel and a liquid crystal display apparatus having a wide viewing angle with less color change with a simple configuration.
