LCD device with address mark connected with wiring

Abstract

Including a transparent substrate (11), a plurality of first gate bus lines (GL) formed on the transparent substrate i ), a plurality of second bus lines (SL j ), a plurality of common electrode lines (CE i ), each of a plurality of pixels (P ij ), a plurality of address marks are formed on a transparent substrate, and each address mark is connected to one of the first bus line, the second bus line and the common electrode bus line.

Description

technical field [0001] The present invention relates to liquid crystal display (LCD) devices, and in particular, to an improvement of an address mark for easy and accurate determination of defect locations of LCD devices. Background technique [0002] The LCD devices of the prior art generally include: a transparent substrate, a plurality of gate bus lines formed on the transparent substrate, a plurality of signal bus lines perpendicular to each gate bus line formed on the transparent substrate, A plurality of common electrode lines parallel to each gate bus line are formed, and a plurality of pixels connected to one of the gate bus lines, one of the signal bus lines and one of the common electrode lines. [0003] During the inspection mode, in order to easily and accurately determine defect positions, a plurality of address marks are provided for the gate bus line (common electrode line) and the signal bus line (see JP-A-2000-147549). This will be described in detail below...

AI Technical Summary

Problems solved by technology

First, when static charge is transferred to an address mark by instantaneous discharge, since the address mark is electrically insulated, the address mark is melted, which will cause defects due to dust

Second, if each address mark is used as a test pad so that the address mark is exposed to the air, the address mark will come off when the rubbing process using a rubbing roller is performed on the address mark, which will also result in damage caused by dust. Bringing defects
