Abstract

See full text

A circuit board (1) includes a plurality of transistor elements on an insulating substrate (2). At least one of the plurality of transistor elements is an oxide TFT (10) including, as a channel layer (11), an oxide semiconductor. At least one of the plurality of transistor elements is an a-SiTFT (20) (i) being different from the oxide TFT (10) in functions as circuit components and (ii) including, as a channel layer (21), an amorphous silicon semiconductor. The oxide TFT (10) is a top gate transistor, and the a-SiTFT (20) is a bottom gate transistor. This provides: a configuration that can (a) enhance the performance of the circuit board equipped with the TFTs differing in their respective functions as circuit components and (b) reduce the area necessary for mounting the TFTs; and a method for producing the circuit board.
