Abstract: A display device includes a display panel configured to display an image. A window laces the display panel and includes a transparent display area configured to transmit the image displayed on the display panel therethrough. A non-display area at least partially surrounds the display area. A light-blocking pattern layer is disposed on the non-display area of the window. A touch member is disposed between the display panel and the window and includes a voltage line. A pressure sensing wiring is disposed between the touch member and the window and at least partially overlaps the voltage line. The voltage line and the pressure sensing wiring overlap the light-blocking pattern layer.
