Liquid crystal display device
View Patent ↗A liquid crystal display device according to the invention includes a first substrate, on a surface of which are formed: a first color film which has a color other than black, and one portion of which configures a first pixel; a second color film, one portion of which configures a second pixel adjacent to the first pixel; a third color film, at least one portion of which configures a third pixel; and a fourth color film, a second substrate, and a liquid crystal layer sandwiched between the first substrate and second substrate, wherein the first color film and second color film have a first overlapping portion in which they overlap each other in the boundary between the first pixel and second pixel, and the fourth color film, being formed on the first overlapping portion, configures a post spacer which defines the space between the first substrate and second substrate.
1. A liquid crystal display device, comprising:
a first substrate on a surface of which are formed,
a first color film which has a color other than black, and one portion of which configures a first pixel,
a second color film which has a color, other than black, which differs from that of the first color film, and one portion of which configures a second pixel adjacent to the first pixel,
a third color film which has a color, other than black, which differs from those of the first color film and second color film, and at least one portion of which configures a third pixel, and
a fourth color film which has a color, other than black, which differs from those of the first color film and second color film;
a second substrate; and
a liquid crystal layer sandwiched between the first substrate and second substrate, wherein
the first color film and second color film have an overlapping portion in which they overlap each other in the boundary between the first pixel and second pixel, and
the fourth color film, being formed on the overlapping portion, configures a spacer which defines the space between the first substrate and second substrate;
wherein the sum of the thickness of the first color film and second color film in the overlapping portion is smaller than the sum of the thickness of the first color film in the first pixel and the thickness of the second color film in the second pixel; and
a conductive film and an insulating film are formed on top of the first pixel, the second pixel, and the third pixel, and a top surface of the fourth color film is such that the fourth color film is exposed.
2. The liquid crystal display device according to claim 1 , wherein the fourth color film is of the same color as the third color film.
3. The liquid crystal display device according to claim 1 , wherein
a plurality of scan signal lines, a plurality of video signal lines, and switching elements provided one in each pixel, are formed on the first substrate.
4. The liquid crystal display device according to claim 3 , wherein
the overlapping portion is provided in such a way as to overlap a scan signal line or a video signal line.
5. The liquid crystal display device according to claim 1 , wherein
the conductive film and the insulating film, which are formed on top of the first pixel, the second pixel and the third pixel, are not formed on the fourth color film configured as the spacer, the fourth color film configured as the spacer being formed directly on the overlapping portion of the first color film and the second color film in the boundary between the first pixel and the second pixel.
