发明名称 LIQUID CRYSTAL DISPLAY PANEL, DISPLAY DEVICE, IDENTIFICATION MARK DETECTOR, DETECTION AND DISPLAY SYSTEM, TFT ARRAY REPAIR DEVICE, AND IDENTIFICATION MARK DETECTING METHOD
摘要 PROBLEM TO BE SOLVED: To provide the device and method capable of effectively performing processing on pixel areas of a display device. SOLUTION: On each pixel area 41 on a liquid crystal TFT array substrate, an ITO transparent electrode 43, a gate line 48, a data line 46, a TFT active element 45, an identification mark 50, etc., are formed. The identification mark 50 is provided on the gate line 48 by forming a silver bar code. Since the identification mark is provided in the pixel area, it is possible to surely identify the transistor to be repaired, by detecting the identification mark, for instance, in repair processing of a TFT array substrate. Moreover, in an information processor for inputting graphics and characters onto a screen by using a laser pen, it is possible to accurately specify a locus of the pen by specifying a position of the pixel area from the identification mark detected by the pen, and to recognize inputted graphics, etc., in details.
