Patent ID: 7751008

Claim:
A method of manufacturing a liquid crystal display in which a first substrate having a TFT array and a conductive film forming a pixel portion driven by said TFT array in a display area, and a second substrate are bonded with a gap interposed therebetween and a liquid crystal is held in said gap, comprising: a TFT array forming step of forming said TFT array on said first substrate in a first region and forming a barrier of the same materials as a plurality of materials constituting said TFT array in a second region different from said first region in at least part of a neighborhood of said display area at the same time; and a contact hole forming step of forming a contact hole for connecting a source terminal or a drain terminal in said TFT to said conductive film and etching a contour of said barrier at the same time wherein after the etching of the contour of the barrier, the first substrate is exposed between the first and second region.
