A common electrode(11) of the conductive electrode type is put on a transmitting area of the lower glass substrate upper part. The common electrode is coated only on the transmitting area. Also, the common electrode is coated on the reflecting area to control Cst as much as desired. The TFT can be placed in one of the reflecting area or a transmitting area because a pixel electrode and the reflecting electrode are directly connected.

Abstract: A manufacturing method of polarized plate for polarized sunglass using reactive mesogen layer is provided to simply resolve a weak point generated in using a liquid crystal display device by coating reactive mesogen on a top of a polarized plate. A high function polarized plate(12) for a liquid crystal display device includes a reactive mesogen layer and a polyvinyl alcohol layer. The reactive mesogen layer is positioned on a top layer of the polyvinyl alcohol layer, and performs role of TAC(Triacetyl Cellulose) film. The polyvinyl alcohol layer performs role of a polarizer. The reactive mesogen layer prevents blocking of a light by a polarized light sunglass(16) by breaking a light transmitting a bottom polarized plate, a liquid crystal layer(14), and the polyvinyl alcohol layer.
