Abstract: A display device includes a support plate including first to third regions, and a display panel divided into first to third display regions overlapping the first to third regions, and including light emitting elements (LEs) and pixel circuits (PCs). The second display region includes a first partial region in which first and second PCs, and a first LE are disposed, and a second partial region in which a second LE is disposed. The third display region includes a third partial region in which third and fourth PCs, and a third LE are disposed to overlap a first support portion of the third region, and a fourth partial region in which a fourth LE is disposed to overlap each opening in the third region. A first separation distance between the second PC and the second LE is less than a second separation distance between the fourth PC and the fourth LE.
