A color filter is provided on the surface of a substrate that opposes liquid crystals. The color filter has a surface profile defining the state of alignment of the liquid crystals. More specifically, the color filter has a plurality of alignment control protrusions whose top portions extend in one direction. A thin alignment film is formed so as to cover the color filter having such a surface profile.
