Abstract
The circuit board (1) of the present invention includes a plurality of transistor elements provided on a single insulating substrate (2) for respective pixels that are two-dimensionally arranged or respective pixels in a group of a predetermined number of the pixels. At least one of the plurality of transistor elements is an oxide TFT (10) having a channel layer (11) formed by an oxide semiconductor, and at least another of the plurality of transistor elements is an a-Si TFT (20) having a channel layer (21) formed by, for example, an amorphous silicon semiconductor. Each of the oxide TFT (10) and the a-Si TFT (20) is a bottom-gate transistor.
