Abstract
The occurrence of the poor electric connection between the outer circuit and the liquid crystal display device can be reduced in the manufacturing method of the outer circuit and liquid display device of this invention. The liquid crystal display device has the pixel regionP and the outer connection region. There are the gate metal layerdisposed on the gate insulating film, the interlayer insulating filmcovering the gate metal layer, the first conductive layercovering the gate metal layerlocated on the interlayer insulating film, the passivation filmwith the second openingexposing the part of the first conductive layerthat covers the gate metal layer, and the second conductive layercovering the first conductive layerexposed from the second openingin the outer connection region. The metal bumpof the outer circuit is connected on the second conductive layerthrough thermal pressure treatment.
