Abstract
The display device according to the present invention includes: a liquid crystal layerhaving a first principal face and a second principal face opposing each other; a plurality of electrodesand; a fluorophore layer provided on the first principal face side of the liquid crystal layer; and an illuminator for emitting light for exciting the fluorophore layer toward the second principal face of the liquid crystal layer. When a predetermined voltage is applied, the liquid crystal layer forms an intermediate layer containing liquid crystal molecules which are oriented in a different direction from that of liquid crystal molecules in an anchoring layer near the second principal face, and causes linearly-polarized light which has been transmitted through the anchoring layer near the second principal face to be refracted toward the second principal face in or near the intermediate layer. Displaying is conducted by using light emitted by the fluorophore layer while no voltage is applied across the liquid crystal layer, and black displaying is conducted while a voltage is applied across the liquid crystal layer.
