The object of the invention is to provide a display apparatus that can partially eliminate the need for a backlight unit and that achieves a corresponding reduction in thickness. The display apparatus includes two display panels arranged one on top of the other and each having two transparent substrates disposed opposite each other with a liquid crystal layer provided therebetween, and the first display panel has a reflective layer, a light-guiding transparent substrate, and a light control layer, and the second transparent substrate, reflective layer, light control layer, and light source together constitute an illuminating means for illuminating the second display panel which is an illuminated member, with provisions made to illuminate the second display panel by the light emerging from the light-guiding transparent substrate.
