DISPLAY DEVICE

Abstract

The present invention prevents the corrosion of a printed circuit board which is connected to a lower side of a display panel in a liquid crystal display panel. In a display device which includes a display panel and a frame member which supports an outer peripheral portion of a display screen of a display panel, a water absorbing member is adhered to a surface of the frame member which faces the display panel in an opposed manner.
