Abstract
To provide a semiconductor device in which external correction can be performed, the area occupied by a read circuit is reduced, and power consumption is reduced. One embodiment of the semiconductor device includes a pixel and a read circuit. The pixel includes a transistor and a display element. The read circuit includes a function selection portion and an operational amplifier. The transistor is electrically connected to the function selection portion through a wiring. The operational amplifier is electrically connected to the function selection portion. The function selection portion includes at least one switch. The function selection portion can select a function of the read circuit by controlling the switch.
