Abstract
A display device capable of obtaining a bright display is provided. A polarizer is arranged above an TN liquid crystal, a light-scattering layer, a polarized light separator, a coloring layer, and a reflecting plate are arranged under the TN liquid crystal. The polarized light separator transmits a linearly polarized light component of a second direction of light being incident from the upper side, reflects a linearly polarized light component of a third direction perpendicular to the second direction, and can upwardly emit linearly polarized light of the second direction in response to light being incident from the lower side. In a voltage non-applied portion, light reflected by the polarized light separator becomes white emission light. In a voltage applied portion, light transmitted through the polarized light separator is colored by the coloring layer to be color emission light.
