Liquid crystal display capable of reducing amount of return light to TFT and manufacturing method therefor

Abstract

There is provided a liquid crystal display device, as well as a manufacturing method therefor, capable of preventing characteristic deterioration of TFTs by reducing the amount of return light incident on the TFTs. A light interception thin film 2 is composed of a silicide film formed on a transparent substrate 1 and a polysilicon film formed so as to cover a top of the silicide film, and a polysilicon film 3 is formed so as to cover a top of the light interception thin film 2. Then, by making up a light interception film from the light interception thin film 2 and the polysilicon film 3, the light interception effect on a TFT-use polysilicon layer 5 formed over the light interception film with interposition of the transparent insulation film 4, and enough thermal resistance and adhesion can be obtained in the TFT manufacturing process.
