Abstract:
1. A method for manufacturing a liquid crystal display device comprising the steps of: forming a first inorganic insulating film over a first substrate by radio frequency sputtering; forming a second inorganic insulating film over a second substrate by radio frequency sputtering; forming a pixel electrode over the first substrate; forming an opposing electrode over the second substrate; forming a columnar spacer over the first substrate for spacing evenly between the first substrate and the second substrate; drawing and pre-fixating a sealant over the second substrate; dropping a liquid crystal material on a region surrounded by the sealant over the second substrate; pasting the first substrate and the second substrate together under reduced pressure; and fixating the sealant by UV light passed through the second substrate, wherein each of the first and second inorganic insulating films comprises a silicon nitride film containing argon, and wherein each of the first and second inorganic insulating films is a silicon nitride film containing argon at a concentration of from 1×10
