Patent ID: 7084936

Claim:
A display, comprising: a display surface; an electroluminescent panel, wherein the electroluminescent panel has a plurality of electroluminescent elements; and a liquid crystal panel, which overlaps the electroluminescent panel in a front and rear direction of the display, wherein the liquid crystal panel includes a plurality of liquid crystal elements; wherein the electroluminescent elements and the liquid crystal elements are aligned with each other in the front and rear direction of the display, and wherein at least one of the electroluminescent elements and the liquid crystal elements function as pixels to show an image on the display surface, wherein an electric field is applied to each liquid crystal element such that the liquid crystal element is selectively switched between a light-transmitting state and a light blocking state, wherein an electric field is applied to each electroluminescent clement such that the electroluminescent element is selectively switched between a light-emitting state and a non-light-emitting state, wherein the electroluminescent panel is located at the rear of the display surface, wherein the liquid crystal panel is located at the rear of the electroluminescent panel, wherein the liquid crystal panel reflects light that enters from the display surface via the electroluminescent panel at a portion corresponding to the liquid crystal element that is in the light-transmitting state, and wherein, when the electroluminescent elements function as pixels, an electric field is applied to the liquid crystal elements such that the liquid crystal elements are kept in a light-blocking state.
