Abstract: A display device includes a display panel, first circuit board, a second circuit board, a first adhesive element, and a conductive element. The display panel includes a non-bending region and a bending region that is bent from the non-bending region. The bending region includes a curvature region having a specific curvature and a facing region facing the non-bending region in a thickness direction of the display module. The first adhesive element is disposed to combine the first circuit board with the second circuit board, and the conductive element is disposed to electrically connect the first circuit board to the second circuit board.
