A color filter which is able to form a liquid crystal display device that has few variation in display caused due to difference in exposure illuminance among exposure heads and/or misalignment in pattern position, and that is excellent in display quality, and an exposure mask used for producing the color filter are provided. A color filter 1 includes: a substrate 2; black matrixes 3 provided on the substrate 2; and a plurality of colored layers 4 which partially overlap the black matrixes 3 in at least a first direction. The widths of overlap portions 5 in which the black matrixes 3 and the colored layers 4 overlap each other in the first direction are varied over the entirety of a display area, and the degree of the variation is uniformly distributed over the entirety of the display area. As a result, even if the sizes of the overlap portions 5 are partially varied due to misalignment in position of the exposure heads and/or change of exposure condition, the partial variation is blended into the variation of the widths distributed over the entirety of the display area, so that a varied state can be prevented from becoming conspicuous as a whole.
