Abstract:
A liquid crystal display device, comprising:(a) a first substrate being provided including(1) a first transparent sheet,(2) a plurality of gate bus lines disposed parallel to each other on said first transparent sheet,(3) a plurality of drain bus lines formed on said first transparent sheet and adapted to intersect perpendicularly said gate bus lines a second substrate opposed to said first substrate, and a liquid crystal sealed in the gap between said first substrate and said second substrate,(4) pixel electrodes disposed severally in areas formed on said first transparent sheet as defined by said gate bus lines and said drain bus lines,(5) a plurality of thin film transistors connected in series between said pixel electrodes and said drain bus lines and adapted to utilize said gate bus lines as gate electrodes,(6) a first electrode connected electrically to any of connecting parts of sources and drains of said plurality of thin film transistors,(7) an interlayer insulating film covering said thin film transistors and said first electrode,(8) a second electrode made of a light blocking metal film and opposed to said first electrode on said interlayer insulating film, and(9) a black matrix formed to overlie channel parts and the source and drain connecting parts of said plurality of thin film transistors;(b) a second substrate opposed to said first substrate and being provided including(1) a second transparent sheet, and(2) a counter electrode made of a transparent conductor and formed on said second transparent sheet; and(c) a liquid crystal sealed in the gap between said first substrate and said second substrate.
