Patent ID: 6842214

Claim:
A liquid crystal display device comprising: a first substrate on which a display portion, that has a pixel matrix, scanning bus lines and data bus lines, and a peripheral circuit portion, that has gate drivers for driving the scanning bus lines and data drivers for driving the data bus lines, are formed; a second substrate opposed to the first substrate; and liquid crystals put between the first substrate and the second substrate; wherein at least a part of the peripheral circuit portion has first metal patterns formed on the first substrate, a first insulating film formed on the first metal patterns, a second metal pattern formed on the first insulating film, a second insulating film formed on and in contact with the second metal pattern to have at least a first resin film, and third metal patterns formed on the second insulating film and electrically connected to the second metal pattern via a hole formed in the second insulating film, and the display portion having an active element formed on the first substrate and covered with the second insulating film, and a pixel electrode formed in a pixel region on the second insulating film and connected electrically to the active element via a hole that is formed in the second insulating film.
