Abstract:
A liquid crystal display device including,a pair of substrates with a liquid crystal layer interposed therebetween, one of said substrates having thereon a matrix array of thin-film transistors, pixel electrodes as driven by the thin-film transistors, and a pattern of scanning lines and signal lines for supplying the thin-film transistors with voltage signals used for pixel formation, a remaining one of said substrates having color filters of three colors of red and green plus blue, the one substrate also having a peripheral side with scan line lead terminals provided and another peripheral side with signal line lead terminals provided; a scan line drive IC mount region and a signal line drive IC mount region having output terminals connected to respective ones of said scan line lead terminals and said signal line lead terminals of the liquid crystal panel while permitting direct mount of more than one scan line drive IC and more than one signal drive IC respectively; and more than one static electricity suppression common line provided in a cut removal region for commonly connecting said scan line lead terminals and signal line lead terminals together, characterized by comprising: six signal line side common lines provided in the signal line drive IC mount region of the signal line lead terminals connected to said static electricity suppression common line, for connection with six terminal groups as divided from the signal line lead terminals in a way such that the groups are of positive polarity of red, negative polarity of red, positive polarity of green, negative polarity of green, positive polarity of blue, and negative polarity of blue; and test pads provided on said one substrate in an area excluding said signal line drive IC mount region for connection to said six signal line side common lines.
