Display device

Abstract

A display device includes a display panel, a rear case, a printed circuit board (PCB), and a conductive adhesive member. The rear case includes a bottom plate and sidewalls. The bottom plate faces the display panel and the sidewalls are extended from the bottom plate along the display panel. The PCB includes a ground conductive layer and is electrically connected to the display panel. The ground conductive layer is exposed toward the bottom plate. The conductive adhesive member is disposed between the ground conductive layer and the bottom plate and electrically connects them. Accordingly, the PCB and/or its circuit components may be protected from static electricity, which may be discharged through the bottom plate.
