A display device includes a display panel, a lighting device having a light emission surface, a center directive light refraction member imparting a refraction effect to light exiting through the light emission surface to be directed to a middle section of the display panel to generate a much light emission angle range where an emission light quantity is much and a less light emission angle range where the light emission quantity is less in a luminance angle distribution, and an asymmetric light refraction member configured to impart an asymmetric refraction effect to the emission light such that among emission light rays exiting the center directive light refraction member, light rays in the less light emission angle range is directed toward the less light emission angle range while a part of light rays in the much light emission angle range is directed toward the less light emission angle range.
