Abstract

PURPOSE: To obtain the device which makes displaying sufficiently distinctly readable without lighting of lamp in a bright place by using an EL element as a reflecting plate and EL lamp and providing transparent electrode to the polarizing plate adjoining thereto, in the reflection type liquid crystal display device.
CONSTITUTION: In the liquid crystal device formed by sandwiching a liquid crystal layer 43 between transparent plates 41, 42 provided with transparent electrodes, disposing polarizing plates 44, 45 to the top and bottom thereof and providing a reflecting plate 46 to the underside of the polarizing plate 45, the reflecting plate 46 is formed by an EL element as an EL lamp and reflecting plate; in addition, a transparent electrode 47 is provided on the plate 46 side of the polarizing plate 45. The transparent electrode 47 provided in adjacency to the above-mentioned EL element is used for lighting of the EL element in the dark time but at the same time the EL element becomes in state of protected directly by the electrode 47 and polarizing plate 45 and since this eliminates the need for conventional EL element protecting film, the reflection efficiency of the plate 46 imoroves and at the time of using the device in a bright plate, it may be used as the reflecting plate of high reflectance.
