1. A display device comprising:
a first substrate including a display area and a bezel area surrounding the display area, the display area comprising a pixel area where an image is displayed;
a second substrate on the first substrate;
a liquid crystal layer between the first substrate and the second substrate, at least a portion of the liquid crystal layer is in the display area;
a seal member between the first substrate and the second substrate in the bezel area, the seal member surrounding the liquid crystal layer;
a color filter between the first substrate and the liquid crystal layer in the pixel area of the display area;
a black matrix between the liquid crystal layer and the second substrate in the display area and the bezel area, the black matrix including a first opening in the pixel area and a second opening in the bezel area such that the second opening is between the seal member and a boundary between the display area and the bezel area;
a dummy color pattern between the first substrate and the liquid crystal layer in the bezel area; and
a lower planarization layer between the first substrate and the liquid crystal layer, the color filter in the display area and the dummy color pattern in the bezel area covered by the lower planarization layer,
wherein the dummy color pattern overlaps the second opening of the black matrix and the dummy color pattern extends to the boundary between the display area and the bezel area,
wherein the color filter includes a region overlapping with the first opening of the black matrix in the pixel area of the display area,
wherein an upper surface of a portion of the lower planarization layer between the color filter and the first opening of the black matrix in the pixel area has a same level as an upper surface of a portion of the lower planarization layer overlapping with the black matrix in the display area, and
wherein an upper surface of a portion of the lower planarization layer overlapping with the dummy color pattern has a same level as the upper surface of a portion of the lower planarization layer between the color filter and the first opening of the black matrix in the pixel area.
