Abstract
An interconnecting structure and a pixel structure suited to large-sized screens are formed. A counter line/electrode is formed on a TFT substrate, and the counter line/electrode is made of a stacked structure film in which a layer made of aluminum or an alloy essentially containing aluminum is covered with a high-melting point metal film, and a transparent conductive film which covers the stacked structure film.
Claims13
A liquid crystal display device comprising:
- a pair of substrates;
- a liquid crystal layer interposed between said pair of substrates;
- drain lines and gate lines formed on one of said pair of substrates and crossing each other in a matrix form, wherein a region bounded by a pair of said drain lines and a pair of said gate lines defines 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, said counter voltage line including a multi-layered structure comprising a first molybdenum layer, followed by an aluminum layer or an alloy layer comprising essentially of aluminum, followed by a second molybdenum layer;
- a first insulating layer formed on said counter electrode and said counter voltage line;
- a second insulating layer formed on said first insulating layer;
- and
- a pixel electrode comprising a transparent conductive film that is electrically connected to said switching element,
- wherein said counter voltage line intersects said drain lines through said first insulated film,
- wherein said counter voltage line has a first width where it intersects said drain lines and a second width where it does not intersect said drain lines, said first width being different from said second width.
