Abstract: A display panel includes an array substrate, an opposite substrate facing the array substrate, and a liquid crystal layer disposed between the array substrate and the opposite substrate. The array substrate includes a display area and a non-display area surrounding the display area, and the non-display area includes a first non-display area disposed adjacent to a side portion of the display area and a second non-display area other than the first non-display area. The first non-display area overlaps the opposite substrate. The array substrate and the opposite substrate have the same or substantially the same area and a wire member is disposed under the array substrate to be connected to an external circuit module. Accordingly, the display panel does not need an extra space for the wire member, and thus the non-display area is reduced.
