  • Publication number: 20240219785
    Abstract: A display device including a liquid crystal layer is provided. The liquid crystal layer may be disposed between a first substrate and a second substrate. The liquid crystal layer overlapping with a display area may be surrounded by a seal member disposed on a bezel, which is disposed outside the display area. A black matrix between the liquid crystal layer and the second substrate may include first openings in the display area and at least one second opening disposed between the display area and the seal member. A dummy color pattern between the first substrate and the liquid crystal layer may include a region overlapping with the second opening of the black matrix and a region disposed between the display area and the second opening.
