Patent ID: 7408612

Claim:
A display device comprising: scan lines on a insulating substrate; signal lines on the insulating substrate; a display area comprising pixel electrodes connected to the signal lines; a scan line driver circuit connected to the scan lines; a signal line driver circuit connected to the signal lines; a flexible substrate providing at least one of a scan potential to the scan line driver circuit and a signal potential to the signal line driver circuit from outside, wherein the scan line driver circuit and the signal line driver circuit are mounted directly on the insulating substrate in a region outside of the display area closely opposed to a same side of the display area, with the signal lines intersecting with and spaced from the scan lines by an insulating film in the region outside of the display area, and terminals on the insulating substrate for connecting the flexible substrate are connected to the scan line driver circuit or the signal line driver circuit by connecting lines having different lengths, with longer connecting lines being formed wider than connecting lines that are shorter than the longer connecting lines, and the terminals connected to the longer connecting line are also formed wider than terminals connected to the connecting lines that are shorter than the longer connecting lines.
