Abstract

A display device includes first and second circuit boards connected to a display panel defining a display area and a non-display area, and including a first sub-base layer overlapping the display area and the non-display area, a second sub-base layer above the first sub-base layer, a connection electrode between the first sub-base layer and the second sub-base layer, and electrically connected to a signal line, and pad electrodes exposed through an opening in the first sub-base layer, electrically connected to the connection electrode, and including first pad electrodes electrically connected to the first circuit board, and extending in a direction, and second pad electrodes electrically connected to the second circuit board, spaced apart from the first pad electrodes in the direction, and extending in an opposite direction, and a circuit layer including a transistor, and at least one signal line connected to the transistor.
