Patent ID: 7358570

Claim:
A COG (Chip On Glass) type liquid crystal display panel in which a substantially rectangular chip mounting area for mounting an IC chip for driving liquid crystal is provided on one of a pair of substrates on which a plurality of electrodes are arranged in a matrix state, wherein the electrodes are connected to pixels (R, B, G) of different types, liquid crystal is filled between the substrates whose peripheral areas are bonded together by a sealing material, a plurality of extraction electrodes, which are respectively connected to the electrodes, are lead out of said chip mounting area, and terminals for bump, which are connected to bump terminals of said IC chip for driving liquid crystal, are formed on the extraction electrodes, wherein said plurality of extraction electrodes are lead out at least to two sides of said rectangular chip mounting area and are further extended onto said chip mounting area from said terminals for bump, and terminals for inspection are arrayed on extended end portions of the extraction electrodes such that said terminals for inspection are arrayed in a straight line comprising terminals connected to pixels of the same type, to which extraction electrodes lead out from said at least two sides of the rectangular chip mounting area are connected, wherein said extraction electrodes are connected to transparent electrodes respectively corresponding to pixels of R, G and B, via switching elements, said terminal for inspection are used as terminals for inspecting R, G and B corresponding to said respectively connected transparent electrodes for R, G and B, and the terminals for inspection are arrayed in straight lines consisting of terminals for inspecting R, G and B, respectively.
