Abstract
The present invention provides a transflective liquid crystal display device which can reduce the generation of an image retention even when the transflective liquid crystal display device adopts the constitution in which an aluminum film is formed in a reflective region and a transparent conductive film made of ITO or the like is arranged over the aluminum film. The constitution according to the present invention is characterized in that, in a liquid crystal display device which includes a transmissive region and a reflective region within one pixel, a pixel electrode of the transmissive region is formed of a first transparent conductive film, a pixel electrode of the reflective region is formed by stacking an aluminum film on a high-melting-point metal film and by arranging a second transparent conductive film on the aluminum film, and the second conductive film and the high-melting-point metal film in the reflective region are brought into contact with each other at an end portion of the high-melting-point metal film.
