ABSTRACT:
A reflective liquid crystal display device comprises a substrate, a transparent substrate facing the substrate, and a liquid crystal layer sandwiched between the substrate and the transparent substrate, and further comprises first transparent electrodes, an electrically insulating separating layer and a reflective film formed in that order from the liquid crystal layer side at the inward-facing surface of the substrate, and also comprises a second transparent electrode included in the inward-facing surface of the transparent substrate. The electrically insulating separating layer physically and electrically separates the reflective film made of Al from the first transparent electrodes, so that durability against chemicals at processing and reliability are improved.
