Abstract

A display device includes a backlight unit, a light guiding plate which is overlappingly arranged on an optical panel, light emitting elements which are arranged on the side surface of the light guiding plate, and a light source driving unit which drives the light emitting elements. The light source driving unit intermittently turns on all of the light emitting elements when displaying a 3D image on the optical panel. In contrast to this, when displaying a 2D image on the optical panel, each light emitting intensity of the light emitting elements in a part of rows is set to be the same as that in a 3D mode, and each light emitting intensity of the light emitting elements in a part of rows other than that is set to be lower than that in the 3D mode.
