Liquid crystal display device

Abstract

Abstract PURPOSE:To contrive the reduction of a disconnection of wiring and the conversion to a low resistance of a wiring resistance by forming a common electrode by a multi-layer structure of two layers and forming the uppermost layer by the same material as that of a picture element electrode, and covering its lower layer with the uppermost layer or an insulation layer for constituting an MIM element. CONSTITUTION:On a substrate 1, a common and lower electrode 2 is accumulated and formed by using a high conductive material and it is converted to a prescribed pattern, and also, on its common and lower electrode 2 or the substrate 1, an insulation film 4 is accumulated and formed and converted to a prescribed pattern. Subsequently, an upper and auxiliary electrode 5 is formed on them by using the same material as that of the common and lower electrode 2, and thereafter, a transparent picture element electrode 6, and a transparent electrode 3 for forming the uppermost layer of the common electrode are accumulated and formed simultaneously by the same transparent electrode material. Next, a pattern of a display picture element part and a pattern of a transparent electrode part are provided, so that the pattern of the latter covers an exposed part of the common and lower electrode 2, and also, does not come into contact with the upper and auxiliary electrode 5. In such a way, the wiring resistance becomes low, and also, the disconnection is corrected naturally by the transparent electrode, and the yield is improved.
