Abstract: Provided are a display apparatus and a method of manufacturing the display apparatus. A color filter layer including at least a red color filter, a green color filter, and a blue color filter is disposed on a first substrate. A black matrix is disposed on the color filter layer. A color filter overlapped unit where the red, green and blue color filters are overlapped is disposed in a black matrix area corresponding to the black matrix. The color filter overlapped unit has a lower reflectivity with respect to an external light than the other color filters. The color filter overlapped unit is formed in the black matrix area, and the color filter overlapped unit is formed by overlapping the blue, red and green color filters in order, and, thus, can prevent mixing of colors and reduce reflection with respect to an external light.
