Patent ID: 6897907

Claim:
A liquid crystal display device comprising: a circuit array substrate; a counter substrate provided opposite to said circuit array substrate; a liquid crystal layer held between said circuit array and counter substrates; and sealant to seal the liquid crystal layer at a periphery of said circuit array and counter substrates, said circuit array substrate including, pixel electrodes disposed in matrix on said circuit array substrate, signal and scanning lines crossed substantially at right angles, a connecting pad provided along at least one edge portion of said circuit array substrate, a connecting portion connected to said connecting pad, an electric power supply line, a first electric power supply terminal extending from said power supply line, a redundant electric power supply line extending from said connecting pad, first contact holes, containing a first electrically conductive film connecting (i) said first power supply line to said connecting pad, and (ii) said first contact holes to each other, second contact holes containing a second electrically conductive film connecting (i)said redundant electric power supply line to said first power supply terminal, and (ii) said second contact holes to each other, said counter substrate including, a counter electrode provided opposite to regions of said pixel electrodes, and a second electric power supply terminal provided on a part of said counter electrode, and an inter-substrate electrically conductive material provided between said array and counter substrates and configured to electrically connect said second electrically conductive film to said second power supply terminal.
