Patent ID: 7884915

Claim:
A method of manufacturing a liquid crystal display device, comprising: forming an array substrate on an insulating substrate, comprising: forming a metal protection pattern at a peripheral region of the insulating substrate to protect corner regions from damage during a masking process; forming a main seal line to a predetermined thickness within an interior region of the array substrate, wherein the main seal line is spaced apart a first distance from the insulating substrate by at least one layer; forming a first auxiliary seal line between the main seal line and the metal protection pattern on the insulating substrate and to the predetermined thickness, wherein the first auxiliary seal line is spaced apart a second distance from the insulating substrate by at least one layer; forming a second auxiliary seal line parallel to and spaced apart from the first auxiliary line, wherein the second auxiliary line does not overlap the metal protection pattern; forming a third auxiliary seal line parallel to and spaced apart from the first and second auxiliary lines, wherein the third auxiliary seal line does not overlap the metal protection pattern; and attaching a color filter substrate to the array substrate, wherein the first auxiliary seal line does not overlap the metal protection pattern, wherein the first auxiliary line is spaced apart 8500 Å from the insulating substrate, wherein the first auxiliary seal line is formed on a protection layer, a gate insulating layer, and a gate electrode metal layer formed on the insulating substrate.
