Liquid crystal display device.
Abstract
In the present invention, a first arm piece for fixing a liquid crystal display element and a second arm piece for fixing a reflecting plate are interconnected at their base portions to form a frame, and a printed circuit board which carries thereon a liquid crystal display element driving circuit connected electrically to the liquid crystal display element is fixed to the back of the reflecting plate, in which construction the angle between the liquid crystal display element and the reflecting plate can be set and maintained stably. Further, a light conductor is disposed on a rear face side of the liquid crystal display element and a light transmission control member is disposed on a rear face side of the light conductor whereby an internal light emitted from an internal light source for illumination of the liquid crystal display element is prevented from leaking to the observer side, that is, it can be conducted in a direction not obstructing the observer's sight.
