PROBLEM TO BE SOLVED: To provide a self-illuminative and outside light-illuminative (dually illuminative) liquid crystal display device provided with a translucent and reflective layer, which is made so thin and lightweight that it is difficult to be achieved in the case of the liquid crystal display device having a side light type light guide plate and has excellent display quality. SOLUTION: This liquid crystal display device has a liquid crystal display panel (1) provided with at least a liquid crystal cell formed by interposing a liquid crystal (30) between a rear side substrate and a visible side substrate. The rear side substrate is prepared by forming at least a transparent layer (14) having a refractive index lower than that of a transparent substrate (10) and the translucent and reflective layer (11) for transmitting and reflecting light on the substrate (10). The visible side substrate is prepared by forming a transparent electrode (21) on another transparent substrate (20). These substrates are arranged so that the electrode sides of them are made opposite to each other. This display device has also illuminators (5) arranged on one or more side faces of the panel (1) and an optical path controlling layer (4) having the refractive index higher than that of the layer (14) and a plurality of optical path changing slopes (A1) which are formed on the outside of the rear side substrate and each of which has 35-48 deg. angle of inclination with respect to the reference plane of the rear side substrate. |
