PROBLEM TO BE SOLVED: To efficiently radiate the heat of a video display element in order to achieve the brightness of a video display device and both of higher image quality and higher performance. SOLUTION: Materials having non-crystallinity and high thermal conductivity are used for translucent materials for the incident and exit surfaces of the video display element, by which the dealing with higher luminance is made possible without degrading the image quality.
