Color filter and color filter manufacturing method

摘要

A color filter having excellent display quality is provided by a continuous exposure method using a compact photomask. The color filter includes: a substrate; a black matrix formed on the substrate, for dividing the substrate into rectangular display regions in which the plurality of pixels are arrayed, and non-display regions surrounding the display regions; a stripe pattern; a plurality of columnar spacers disposed in the display regions; and a plurality of dummy columnar spacers. The stripe pattern includes a plurality of colored layers extending in one direction. Each colored layer intersects with a pair of sides of the display region in a direction perpendicular to the direction in which the colored layers extend. The thickness of both end portions of each colored layer disposed on the non-display region is not uniform. The dummy columnar spacers are disposed in portions of the non-display regions, where the colored layers are absent.

主权项

1. A color filter in which a plurality of pixels are arrayed in a first direction and a second direction perpendicular to the first direction, the color filter comprising:
a substrate; a light-shielding layer formed on the substrate, for dividing the substrate into rectangular display regions in which the plurality of pixels are arrayed, and non-display regions surrounding the display region; a stripe pattern comprising a plurality of colored layers extending in the first direction, each of the colored layers linearly extending in the first direction and intersecting with a pair of sides of the display region in the second direction, in which the thicknesses of both end portions in the first direction of each colored layer disposed on the non-display region are not uniform, and a portion of the stripe pattern in which the thickness of one of the both end portions in the first direction is not uniform has a length along the first direction equal to or larger than 300 μm; a plurality of columnar spacers disposed in the display regions; and a plurality of dummy columnar spacers disposed in portions of the non-display regions, where the colored layers are absent, wherein end portions, of the plurality of columnar spacers and the plurality of dummy columnar spacers, that are farther away from the substrate are each coplanar with each other on a plane parallel to the substrate.
