Abstract: A display device includes a substrate, display elements, a window, and a photo sensor array. The substrate includes a display area and a non-display area. The display elements overlap the display area. The window is disposed on the substrate. The photo sensor array is disposed between the substrate and the window. The photo sensor array is configured to sense three-dimensional pattern information (e.g., epidermal ridge information) of a user via light reflected from a touch input of the user. One or more of the display elements is configured to illuminate a contact area of the touch input with the light.
