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.
Claims6
A liquid crystal display device comprising:
- an insulating substrate;
- a plurality of scan lines and a plurality of signal lines arranged in a matrix form on the insulating substrate;
- a switching active element that is provided for every pixel at each cross portion of the scan lines and the signal lines and connected to each of the scan lines and each of the signal lines;
- colored films of a plurality of colors formed on the switching active element;
- an array substrate having pixel electrodes that are formed on the colored films and driven by the switching active elements;
- a first pattern formed in the colored film;
- and
- a second pattern that is formed in the colored film and fitted to the first pattern formed in a colored film adjacent to the colored film, wherein the first pattern of at least any one of the colored films is a projection pattern projecting to the adjacent colored film, and has a columnar spacer formed on the projection pattern.
