    Abstract: A display device includes a display area which displays an image, and a non-display area disposed around the display area and including a pad part. The display area includes pixels of a first pixel row which are pixels arranged in a first direction along the first pixel row, pixels of a second pixel row, which are pixels arranged in the first direction along the second pixel row next to the first pixel row, and pixel circuits of a first circuit row which are pixel circuits arranged in the first direction along the first circuit row, where the pixel circuits of the first circuit row are electrically connected to the pixels of the first pixel row, respectively. The first pixel row and the first circuit row are spaced apart from each other with the second pixel row interposed therebetween.
