Abstract
A color filter plate, a color filter plate fabrication method and a display panel are provided. The color filter plate comprises a substrate and a plurality of color barriers alternately arranged on the substrate. Each color barrier includes two edge portions and one body portion between the two edge portions. The plurality of color barriers further comprises a plurality of first color barriers, and at least one edge portion of each first color barrier is thicker than the body portion of each first color barrier.
Claims19
A color filter plate, comprising:
- a substrate;
- and
- a plurality of color barriers alternately arranged on the substrate, wherein each color barrier includes two edge portions and one body portion between the two edge portions;
- the plurality of color barriers comprises a plurality of first color barriers;
- and
- at least one edge portion of each first color barrier is thicker than the body portion of each first color barrier.
A display device, comprising:
- an array substrate;
- a color filter plate comprising a substrate and a plurality of color barriers alternately arranged on the substrate, wherein:
- each color barrier includes two edge portions and one body portion between the two edge portions;
- the plurality of color barriers comprises a plurality of first color barriers;
- and
- at least one edge portion of each first color barrier is thicker than the body portion of each first color barrier;
- and
- spacers between the color film substrate and the array substrate.
The display device according to claim 10, wherein:
- the color barrier beneath the spacer has a same thickness as the body portion of the color-resist;
- and
- the spacers are disposed to areas beyond the edge portions of the color barriers.
A color filter plate fabrication method, comprising:
- forming a black matrix on a substrate through a patterning process;
- coating and curing a first color layer on a substrate;
- exposing the first color layer through a first photomask having a plurality of opaque regions, a plurality of transparent regions and a plurality of partially transparent regions;
- and
- developing the first color layer to form a plurality of first color barriers having two edge portions and one body portion between the two edge portions, wherein the edge portion of the first color barrier is thicker than the body portion of the first color barrier, and the partially transparent region of the first photomask corresponds to the body portion of the first color barrier.
