Abstract
According to one embodiment, a display device comprises first and second substrate having light transmissivity and opposing each other, a light-modulating layer arranged between the first substrate and the second substrate, a light source unit which illuminates the light-modulating layer from an outer side of a position which opposes a display area, along a normal direction, first to third color filters of different colors arranged on the first substrate, and first to third electrodes which oppose the first to third color filters, respectively, the light-modulating layer being able to change light dispersibility of each of regions which oppose the first to third color filters according to the electric field produced by each respective one of the first to third electrodes.
