Abstract
The object of this invention is to provide a liquid crystal display that is able to realize a sequential color illumination method, i.e. that can advantageously achieve a high resolution full color display with no need of any color filters. For the purpose of attaining the object above, this invention provides a liquid crystal display characterized by being provided with a display panel in which a phase compensation plate is disposed in front of a bend oriented liquid crystal cell with a cell gap of 7 .mu.m, said cell and phase compensation plate being inserted between two cross polarizers between a TFT active matrix driving each image element by dividing said display panel into elements in a matrix array, and a surface light source sequentially illuminating three color lights of red, green and blue on the rear fare of the display panel.
