ACTIVE MATRIX SUBSTRATE, DISPLAY PANEL, DISPLAY DEVICE, AND ACTIVE MATRIX SUBSTRATE MANUFACTURING METHOD

摘要

An active matrix substrate (101A) comprises a transparent substrate (10), a wiring formed on the transparent substrate (such as L G , L D , L P , L1, and L2), a transparent semiconductor layer (44) that covers at least a part of the wiring, and a transparent insulating film that covers at least a part of the wiring and of the transparent semiconductor layer. The wiring comprises a first metal wiring (41M) serving as a main wiring and a transparent wiring (such as 41, 42, and 43) that branches from the main wiring and serves as a sub-wiring. At least a part of the first metal wiring serving as the main wiring is formed by using a material that has a higher conductivity than that of a material for a wiring serving as the sub-wiring.
