Abstract

A display device includes a display panel, and a circuit film disposed under the display panel. The display panel includes a base layer, pixels disposed on the base layer, sensors disposed on the base layer, first connection lines disposed on the base layer and electrically connected to the pixels, second connection lines disposed on the base layer and electrically connected to the sensors, first pads electrically connected to the first connection lines, and second pads electrically connected to the second connection lines. The circuit film is electrically connected to the first pads and the second pads through an opening of the base layer, and each of the plurality of second connection lines has a straight shape extending along a first direction.
