Zusammenfassung: | PURPOSE:To suppress the temp. rise of the liquid crystal display device body and to improve image quality and reliability by providing a spacing and holding means which disposes the light transparent body of a light source means to face one surface of the device body apart this surface and hold this plate. CONSTITUTION:The light source means 2 is a plastic box-shaped body and is provided with the light transparent plate 22 on the one surface of means. A translucent glass plate, etc., are used for this light transparent plate 22 when the light transparent plate body 11 facing the liquid crystal display device body is not translucent. A light source, such as cold cathode ray tube, having high light emission efficiency is loaded into the light source means 2. An inside surface 23 of the light source means 2 is also formed as a light reflecting surface, mirror surface etc. The light source means is eventually isolated from transferred heat and convectional heat and the propagation of the heat of the light source means to the liquid crystal display device body by the heat transfer means, exclusive of radiation heat is obviated. The temp. rise of the liquid crystal display body is thus suppressed and the image quality is improved. In addition, the reliability is improved and the life is prolonged. |
