A novel structure for the backlight of an LCD is provided, by which the frame portion of the screen can be further narrowed and the weight of the LCD can be reduced. In the backlight arranged in the display area corresponding to the display section of the LCD, the cold cathode tube, disposed along a part of a circumferential area of the display section, is surrounded by a light-introducing plate made of a light-transmitting material and a reflector, and an electro-luminescence lamp is provided between the display section and the reflector.
