Abstract
A liquid crystal display device having an array substrate. The substrate has: (1) an insulating transparent substrate that has a pixel region and a non-pixel region, (2) a plurality of thin film transistors disposed in a matrix pattern on a display screen, each thin film transistor having a gate insulating film that is produced by an atmosphere pressure chemical vapor deposition; (3) a plurality of display pixel electrodes formed on the pixel region of the insulating transparent substrate, each display pixel electrode being connected to each of the thin film transistors; and (4) a protecting film formed on the non-pixel region of the insulating transparent substrate, the protecting film extends from the non-pixel region and overlaps a peripheral portion of each of the display pixel electrodes that are disposed in a portion of the display screen by a width of 2 .mu.m to 7 .mu.m. The display also has a counter substrate that is disposed apart from and facing the array substrate. A sealant layer is disposed at peripheries of the array substrate and the counter substrate so as to seal a space between the array substrate and the counter substrate and is provided with a liquid crystal-inlet port. A liquid crystal layer fills in a space between the array substrate and the counter substrate. The liquid crystal layer being injected in the space from the liquid crystal-inlet port. A closing layer is used to close the liquid crystal-inlet port.
