Abstract:
1. A liquid crystal display device comprising: a pair of substrates; a liquid crystal layer interposed between said pair of substrates; gate lines and drain lines formed on one of said pair of substrates and crossing each other in a matrix form, each crossing one of said drain lines and gate lines defining a pixel; a switching element associated with and disposed relative to each pixel; a sheet-like counter electrode comprising a transparent conductive film arranged at each pixel; a counter voltage line formed on said counter electrode; a first insulating layer formed on said counter electrode and said counter voltage line; and a second insulating layer formed on said first insulating layer, said counter voltage line including a multiplayer structure comprising an upper molybdenum layer, an aluminum layer, or an alloy layer comprising essentially of aluminum and a lower molybdenum layer, wherein said lower molybdenum layer is wider than said upper molybdenum layer.
