ABSTRACT:
A liquid crystal display device includes a substrate having formed thereon pixel electrodes, a counter substrate placed so as to face the substrate, a seal material for bonding the substrate and the counter substrate together so as to seal a liquid crystal in a spacing formed between them, and a protective circuit formed on the substrate so as to connect adjacent scanning lines and/or signal lines, wherein the protective circuit is located inside an outer edge of a bonding region on the substrate where the seal material is applied. In an alternate embodiment, the protective circuit is located inside the inner perimeter of a region where the seal material is applied. A third embodiment employs a bifurcated insulating film layer having at least two separate sections. A first section covers the protective circuit and a second section partially covers the input terminals of the signal and scanning lines. These arrangements permit a stripping-off of the insulating film layer without exposing the protective circuit to air.
