摘要:
A liquid crystal display device includes a liquid crystal display panel and a backlight arranged on a back surface of the liquid crystal display panel, the backlight including a plurality of rod-shaped light sources, a frame which supports the rod-shaped light sources, and a heat radiation plate which is arranged on an inner surface of the frame. Through holes are formed in the frame, and heat radiation fins are formed on the heat radiation plate in a state that the heat radiation fins project toward a back surface of the liquid crystal display panel through the through holes formed in the frame. Due to such a constitution, it is possible to provide a liquid crystal display device which can enhance heat radiation efficiency.
摘要:
A display device includes a display panel unit and a backlight unit which radiates light toward the display panel. The display panel unit includes a display panel on an upper surface of a box-shaped panel housing which has first projecting portions on side walls of the housing. The backlight unit incorporates a light source in a bottom portion of a box-shaped light source housing which has second projecting portions on side walls of the light source housing. By bringing the first projecting portions and second projecting portions into contact with each other, a distance between the light source of the backlight unit and the display panel can be held. Further, by forming third projecting portions which project further than the first projecting portions on the panel housing, handling of the display panel unit is facilitated.

A display device suitable for a game machine has dot printed films which are printed on a light guide plate which constitutes a backlight for illuminating a liquid crystal display panel. The dots of the dot printed films are arranged more densely in a window-frame portion corresponding region, which faces a display region of the liquid crystal display panel, and in the vicinity of an inner periphery of a transmission portion corresponding to a region which faces a transmission region.

A liquid crystal display device includes a liquid crystal display panel and a backlight disposed at a rear surface of the liquid crystal display panel. The backlight includes a light source, a frame housing the light source, a heat dissipating plate disposed inside the frame, and a reflective sheet disposed at a surface of the heat dissipating plate on the liquid crystal display panel side. The heat dissipating plate is formed with a heat dissipating fin protruding to a surface of the frame on the side opposite to the liquid crystal display panel through an opening formed through the frame in a portion corresponding to the upper portion thereof and formed with an opening which is closed with the frame and the reflective sheet in a portion corresponding to the lower portion thereof.
