Abstract
To provide a novel semiconductor device or display device. The semiconductor device includes a decoder circuit, an amplifier circuit, and an arithmetic circuit. The amplifier circuit includes a first amplifier and a second amplifier. One of the first amplifier and the second amplifier has a function of inspecting an output of the other of the first amplifier and the second amplifier. The arithmetic circuit has a function of calculating an error of a potential output from the first amplifier or the second amplifier, on the basis of a result of the inspection. The decoder circuit has a function of correcting a video signal input to the decoder circuit by subtracting the error of the potential from the video signal.
