ABSTRACT:
This invention provides a color filter which comprises, a transparent substrate, color layers of plural colors, a transparent electrode and a protrusion for controlling liquid crystal alignment laminated in this order, and also has plural fixed dot spacers. In a preferable embodiment of this invention, the black matrix is formed by partially overlapping the color layers and the topmost layer of the fixed dot spacers comprises portions of the layer which constitutes the protrusion for controlling liquid crystal alignment or it comprises separate dots of the same composition as that of the protrusion for controlling liquid crystal alignment.This invention can provide a liquid crystal display device that can achieve an excellent display quality and a wide viewing angle and is furthermore excellent in productivity.
