LIQUID CRYSTAL PANEL, MANUFACTURING METHOD THEREOF, AND ELECTRONIC DEVICE USING THE LIQUID CRYSTAL PANEL

摘要

As a mobile display device, a translucent liquid crystal panel is a highly user-friendly display device capable of obtaining a clear image both in a dark place and a light place. However, it is expected to obtain a light-weight and robust display device of lower power consumption, i.e., having the advantages of the transparent type and reflection type liquid crystal panel. A liquid crystal panel having a back surface light emission light source includes: a liquid crystal element formed on a first basic body and sandwiching a liquid crystal element between a transparent first electrode and a transparent second electrode which are arranged to oppose each other; and a back surface light emission light source of the liquid crystal element formed on a second basic body and sandwiching a thin film planar light emitting element between an optically opaque third electrode and a transparent fourth electrode which are arranged to oppose each other. The third electrode is a reflection film arranged on the second basic body side and reflecting external light coming through the liquid crystal layer so as to introduce it into the liquid crystal layer. The fourth electrode is arranged to oppose to the second electrode. The insulation film sandwiched by the fourth electrode and the second electrode is a film formed continuously on the fourth electrode.
