Abstract
According to one embodiment, a display device includes: a plurality of light guide units; a light source; a support substrate; a first electrode transmissive to light provided on the second major surface; a counter substrate opposed to the second major surface and provided away from the first electrode; a second electrode transmissive to light provided on a surface of the counter substrate opposed to the second major surface; and a plurality of spacers provided between the support substrate and the counter substrate and arranged between adjacent ones of the plurality of light guide units when projected onto a plane parallel to the first direction and the second direction. Optical characteristics in a region which is surrounded by adjacent ones of the spacers, the first electrode and the second electrode are changed by a voltage which is applied between the first electrode and the second electrode.
