CIRCUIT BOARD, MANUFACTURING METHOD OF CARD, DISPLAY PANEL AND DISPLAY DEVICE |
摘要 |
FIELD: electricity.SUBSTANCE: invention is referred to circuit board with enhanced corrosion resistance, manufacturing method of the card, display panel and display device. Active matrix underlay (20) contains glass substrate (21); metal conductor (22) made at glass substrate (21); insulating film (24) of the gate covering metal conductor (22); interlayer insulating film (29) covering (24) insulating film (24) of the gate; and transparent electrode (33) shaped at interlayer insulating film (29). Conductor (22) contains contact area (55) where transparent electrode (33) is applied directly to conductor (22). Transparent electrode (33) passes over the contact area (55) so that it covers end surface (29a) of interlayer insulating film (29) faced to contact area (55) and end surface (24a) of insulating film (24) of the gate faced to contact area (55).EFFECT: manufacturing of the circuit board capable to prevent corrosion of metal electrodes due to defects of transparent conductive film that covers end surface of organic insulating film.10 cl, 52 dwg |
