Abstract:
1. A display, comprising: a display surface; an electroluminescent panel, the electroluminescent panel having a plurality of electroluminescent elements; and a liquid crystal panel, which overlaps the electroluminescent panel in a front and rear direction of the display, the liquid crystal panel includes a plurality of liquid crystal elements; the electroluminescent elements and the liquid crystal elements are aligned with each other in the front and rear direction of the display, and at least one of the electroluminescent elements and the liquid crystal elements function as pixels to show an image on the display surface, the display being designed to be able to adjust the brightness of each pixel, the liquid crystal panel being located at the rear of the display surface, and the electroluminescent panel being located at the rear of the liquid crystal panel, an electric field being applied to each electroluminescent element such that the electroluminescent element is selectively switched between a light-emitting state and a non-light-emitting state, and an electric field being 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, the electroluminescent panel reflecting light that enters from the display surface via the liquid crystal panel, and the electroluminescent elements being operated in accordance with the liquid crystal elements such that the electroluminescent element that corresponds to the liquid crystal element that is in the light-transmitting state is switched to the light-emitting state, and the electroluminescent element that corresponds to the liquid crystal element that is in the light-blocking state is switched to the non-light emitting state.
