LIQUID CRYSTAL IMAGE DISPLAY DEVICE AND METHOD FOR RELIEVING ITS DISCONNECTION DEFECT

摘要

PROBLEM TO BE SOLVED: To make it possible to relieve the disconnection defect in video signal lines without limitation and to inexpensively relieve the disconnection of the video signal lines with a small number of parts. SOLUTION: A storage capacitor electrode 13 which is partly superposed on a scanning signal line 12 and a pixel electrode 14, respectively, via a first insulating film is arranged adjacently on the side opposite to the thin-film transistor of the pixel electrode 14 at every pixel unit. A second conductive thin film 20 which is partly superposed on the storage capacitor electrode 13 and the video signal line 11 via a second insulating film is arranged on the side adjacent to the pixel electrode in the longitudinal direction of the video signal line 11 of the storage capacitor electrode 13 at every pixel unit. A third conductive thin film 21 which is partly superposed on the storage capacitor electrode 13 and the video signal line 11 via a third insulating film is arranged on the side adjacent to the pixel electrode in the longitudinal direction of the video signal line 11 of the storage capacitor electrode 13 at every pixel unit.
