Panel device having electrostatic discharge protection

摘要

A display device includes a substrate, at least one signal circuit, a ground protection circuit, and an auxiliary protection circuit. The substrate has a first surface, wherein the first surface includes an active area and a frame area surrounding the active area. The at least one signal circuit is disposed and extending along the frame area and electrically coupled to the active area. The ground protection circuit is disposed and extending along the frame area, wherein the ground protection circuit is positioned at a side of the signal circuit facing an edge of the substrate. The auxiliary protection circuit is disposed and extending along the frame area. The auxiliary protection circuit is disposed between the signal circuit and the ground protection circuit, wherein the auxiliary protection circuit respectively has a gap with the signal circuit and the ground protection circuit, and is electrically conductive.
