LIQUID CRYSTAL DISPLAY DEVICE

Abstract

A projection pattern is formed so as to project to a colored film to which a part of colored film on an array substrate is adjacent. A recess pattern corresponding to the projection pattern is formed to the adjacent colored film. A columnar spacer is formed on the projection pattern. The columnar spacer does not override a color overlap portion of the colored films, and thus the variation in a cell gap between the array substrate and the counter substrate can be suppressed.
