Whole the transparency conducting layer 109 arranged can better anti-external interference, simultaneously because be positioned at the existence of the conductive layer 104 on this transparency conducting layer 109, conductive layer 104 can increase to improve antistatic effect in alternatively non-transparent area thickness, and therefore the thickness of this transparency conducting layer 109 can do very thin.Namely transparency conducting layer 109 and conductive layer 104 are that a shielding is overall, and namely less on transmitance impact, shield effectiveness is good simultaneously, and antistatic effect is strong, greatly can optimize the performance of driving display panels in face.
Alternatively, the thickness of transparency conducting layer 109 is less than or equal to
Alternatively, the thickness of conductive layer is less than or equal to
Alternatively, the annealed technique of transparency conducting layer 109.After the annealed technique of transparency conducting layer 109, material character changes, and cannot be etched away under original etching condition.Then transparency conducting layer 109 after annealing forms conductive layer again, then etch to form conductive layer 104 to conductive layer.When etching conductive layer, transparency conducting layer 109 can not be etched away, and therefore again it need not form protective seam, also eliminate the techniques such as protective seam removal, formation process is simple.
