Abstract
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.
