ABSTRACT:
A lower layer metal wiring is led out from a display portion to a terminal portion provided to the periphery of the glass substrate and covered at the upper surface with an interlayer insulation film. An upper layer metal wiring formed on the interlayer insulation film is connected to the lower layer metal wiring by way of contact holes formed in the interlayer insulation film. The upper layer metal wiring is completely covered by the transparent conductive film. A protective insulation film is formed on the transparent conductive film, and an opening is made in to the protective insulation film in the terminal portion. In the terminal portion, copper foil wirings of a flexible wiring substrate are connected by way of an anisotropic conductive film. The upper layer metal wiring is removed at a portion not protected by the protective insulation film or the anisotropic conductive film.
