ABSTRACT:
An amplifier circuit includes an operational amplifier having first and second input nodes and one output node which is connected to a data line for which a pixel is provided; a feedback circuit having first and second elements which are connected to one of the first and second input nodes at their one ends; and a first switch section. The first switch section switches an operation mode between a first drive mode in which the other end of the first element is connected to the output node and a second drive mode in which the other end of the second element is connected to the output node.
