ABSTRACT:
An improved liquid crystal display incorporates a photoelectric conversion device in order to provide a display suitable for a lap-top personal computer system such as a wordprocessor. The display is provided with a fluorescent lamp for illuminating the display area from the behind of the liquid crystal display. The light rays emitted from the lamp which are not directed to the display area but toward the opposite direction are collected by the conversion device.
