The first dummy pattern is formed in a peripheral area surrounding the display area. The first dummy pattern has a color identical to one of the colors. An edge portion of the first dummy pattern corresponding to an apex of the display area is rounded. Therefore, the reliability of a color filter manufacturing process may be improved, the reliability of the color filter may be improved, and the generation of stain defects having a radial shape may be prevented, so that display quality may be improved.
