Liquid crystal display
First Claim
1. A liquid crystal display device where a first substrate having a display electrode and a second substrate having an opposite electrode are disposed so as to be opposed to each other via a predetermined clearance, and a liquid crystal display element having a liquid crystal layer is provided in the clearance, wherein an electroluminescent element is provided between the first substrate and the second substrate, the liquid crystal display element includes a first reflection film that reflects light from an external light source, and the electroluminescent element includes a second reflection film different form the first reflection film.

Abstract
An EL element (33) is provided on a first substrate (1) to make it possible to perform both light emission display according to the EL element (33) and reflective display according to a liquid crystal display element. An EL control switching element (17) and a liquid crystal layer switching element (18) are provided on a face of the first substrate (1) positioned on the side of a liquid crystal layer (51). The EL control switching element (17) is connected to an anode electrode (21) or a cathode electrode (24) constituting the EL element (33). By connecting the liquid crystal layer switching element (18) to a display electrode (31) and a reflective electrode (28) constituting a liquid crystal display element, a liquid crystal display element and a light emitting element are integrated in a liquid crystal display device incorporated with the liquid crystal display element therein, so that thinning and weight reduction are achieved considering electrical connection therebetween and both reflective display and transmissive display are made possible.
