Abstract
Abstract A liquid crystal television receiver has a main frame including a reflecting plate and a hood member with a liquid crystal display panel and an electroluminescence panel. The reflecting plate is disposed so as to slant with respect to the liquid crystal display panel, and provides a display of a picture from the display panel in a reflecting manner. The electroluminescence panel is slidably provided in the hood member. For illuminating the liquid crystal display panel, the electroluminescence panel is slid above the liquid crystal display panel.
