Patent ID: 8654299

Claim:
An active matrix substrate comprising a data signal line, a scanning signal line, a transistor connected with the data signal line and the scanning signal line, and a pixel electrode connected with the data signal line via the transistor, (i) a first metal layer, which is a material of the scanning signal line, (ii) a gate insulating layer, (iii) a first amorphous silicon layer containing no impurity, (iv) a second amorphous silicon layer containing an impurity, and (v) a heat resistant metal layer being provided in same contour patterns and in this order in an overlapping manner on a substrate, a side surface of the first metal layer, a side surface of the gate insulating layer, a side surface of the first amorphous silicon layer, a side surface of the second amorphous silicon layer, and a side surface the heat resistant metal layer being in direct contact with a transparent insulative resin provided on the substrate.
