    IPC: H01L27/32

    Abstract: A display device includes: a substrate that includes a first area and a second area; a plurality of pixels included in the first area; and a dummy pattern included in the second area, wherein a size of the dummy pattern is smaller than a pixel area corresponding to a first pixel among the plurality of pixels, a ratio of an area occupied by a pixel pattern of the first pixel with respect to the pixel area is a first value, a ratio of an area occupied by the dummy pattern with respect to a dummy area is a second value that is greater than the first value, and the dummy area and the pixel area have the same size as each other.
