Liquid crystal display

A liquid crystal display comprising a display means for displaying characters and graphics, said means including a display portion comprising at least a liquid crystal panel; an illuminating means for illuminating the display portion of the liquid crystal panel; and a converging means for converging light rays from the illuminating means at the display portion of the liquid crystal panel. The illuminating means comprises a lamp (87), a light-guiding plate (83) for receiving therein light rays of the lamp (87) through a lateral surface thereof and for uniformly propagating and diffusing the light rays therein, a reflecting plate (84) disposed on the rear surface of the light-guiding plate (83) to reflect light rays from the rear surface of the light-guiding plate (83), and a diffusing plate (82) disposed on the front surface of the light-guiding plate (74) to diffuse light rays from the front surface of the light-guiding plate (83) and the converging means (81), the light-guiding plate (83), the reflecting plate (84) and the diffusing plate (82) are integrally welded to each other at at least one peripheral position (89a) not affecting the display portion of the liquid crystal panel (85).
