Abstract:
The display device includes a liquid crystal panel including a polymer dispersed liquid crystal (PDLC) layer and a light source, the PDLC layer containing a polymer network and liquid crystal components dispersed in the polymer network, the light source being apart from the liquid crystal panel with an air layer, and configured to emit light toward the liquid crystal panel from an oblique direction, the end portion and the central portion of the PDLC layer each having, in the scattering state, an angle dependence which changes a transmittance of light to be emitted from a front surface based on an angle at which light is incident on a back surface of the PDLC layer, with the angle dependence of the end portion being different from the angle dependence of the central portion, the light source irradiating the end portion and the central portion with light at different angles.
