Abstract: A display panel includes an upper display substrate. The upper display substrate includes a base substrate and first to fourth color filters. The first and second color filters overlap first and second pixel areas. The third color filter overlaps a light-blocking area and a third pixel area and has a first opening and a second opening corresponding to the first pixel area and second pixel area, respectively. The fourth color filter overlaps the first pixel area and the second pixel area and has a third opening corresponding to the third pixel area.

Abstract: A display panel includes an upper substrate to which external light is incident, a sealing member which is in a non-display area and couples the upper substrate to a lower display substrate. The upper display substrate includes: a base substrate; a light shielding layer and filter layer each corresponding to the non-display area and absorbing a portion of external light which is transmitted through the base substrate at the non-display area, the filter layer and the light shielding layer having different colors from each other. In a first non-display area of the base substrate which corresponds to the sealing member, only one among the filter layer and the light shielding layer is disposed. In a second non-display area of the base substrate which is adjacent to the first non-display area, both the filter layer and the light shielding layer are disposed.
