Abstract: A display apparatus includes a first color filter, a second color filter spaced apart from the first color filter, and a light blocking pattern disposed between the first color filter and the second color filter, and making contact with the first color filter and the second color filter. A thickness of the light blocking pattern is smaller than a thickness of the first color filter or a thickness of the second color filter. An upper surface of the light blocking pattern is lower than an upper surface of the first or second color filter by a first height, and the light blocking pattern does not include a photosensitive material.
