Liquid crystal display device having an extention metal film wiring which is covered by polyimide layer having low viscosity under 1.0 poise before curing
First Claim
1. A liquid crystal display device comprising:
- upper and lower substrates with electrodes on the inner surfaces thereof, at least one of said upper and lower substrates including an extended portion thereof which projects beyond the edge of the other substrate,liquid crystal material sandwiched between said upper and lower substrates,a sealing member disposed around the periphery enclosing said liquid crystal material,a driving integrated circuit chip mounted on the inner surface of said extended portion,metal film wiring formed on the inner surface of said extended portion mechanically and electrically connected to said driving integrated circuit chip via solder,a first resin coating comprising polyimide and covering said metal film wirings,and a second resin coating covering said first resin coating for filling up pinholes in the first resin coating and being of low viscosity under 1.0 poise before curing.
