Abstract
A liquid crystal material having a negative dielectric constant anisotropy is provided between first and second substrates and aligned homeotropically. Pixel electrodes each having a slit are provided on the first substrate. Color filters for giving red, green and blue are arranged in the pixels. A projection pattern is formed on the second substrate so as to divide the pixels into small areas. The slit of each pixel electrode is spaced from the projection pattern so as to divide, together with the projection pattern, the pixels into domains. The width of the slit of a pixel among the red, green, and blue pixels is different from that of the other pixel. The coloring of the display screen occurring during white display is suppressed.
