A liquid crystal display device related to the present invention can reduce a stress applied to a crystal liquid panel and prevent unevenness in a display of the liquid crystal panel. This liquid crystal display device includes the crystal liquid panel having an upper substrate and a lower substrate facing each other, a transparent protection plate provided on the upper substrate of the liquid crystal panel, a transparent elastic adhesive material that fills a space between the liquid crystal panel and the transparent protection plate, and a planar light source unit that emits light from the lower substrate side of the liquid crystal panel. The planar light source unit has a frame that includes transparent protection plate supporting portions for supporting end portions of the transparent protection plate from below.
