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.

Abstract: A photo mask includes a transparent substrate, a transflective member, and a light shielding member. The transparent substrate has a transflective region including a first region, a second region located in opposing lateral portions of the first region, and an edge region located adjacent to the first and second regions, and a light shielding region surrounding the transflective region. The transflective member is disposed in the first, second and edge regions under the transparent substrate, and has a different light transmittance in each of the first, second and edge regions. The light shielding member is disposed in the light shielding region under the transparent substrate, and defines an opening which exposes the transflective region. The light shielding member includes a long side extending in a first direction parallel to an upper surface of the transparent substrate and a short side extending in a second direction.
