DISPLAY DEVICE SUBSTRATE, METHOD FOR PRODUCING THE SAME, AND DISPLAY DEVICE

摘要

An active matrix substrate (20) includes: a gate electrode (11) provided on an insulating substrate (10a); a gate insulating layer (12) covering the gate electrode (11); an oxide semiconductor layer (13) provided on the gate insulating layer (12); and a protective layer (17) covering the oxide semiconductor layer (13). The active matrix substrate (20) has a display region (D) where an image is displayed and a gate terminal region (Ts) located around the display region (D) and including a gate terminal (26) for connection to an external circuit. The gate terminal (26) includes a terminal line (21) provided on the insulating substrate (10a). The terminal line (26) is made of a conductive material different from a material constituting the oxide semiconductor layer (13).
