Abstract: A display device includes a base layer, a pixel disposed on the base layer, a signal line electrically connected to the pixel, a signal pad connected to the signal line, and a plurality of insulating layers disposed on the base layer. The signal pad includes a first conductive pattern connected to an end portion of the signal line, a second conductive pattern connected to the first conductive pattern, and at least one insulating pattern disposed between the end portion of the signal line and the second conductive pattern in a cross-sectional view and overlapping the second conductive pattern in a plan view.
