A driver circuit controls an output unit that switches whether or not to supply a current to an output line, in accordance with a potential difference between a first control signal to be input and a voltage of the output line. The driver circuit has a control line transmitting the first control signal to the output unit; a connection switching unit switching whether or not to connect the control line and the output line; a pre-stage control unit that is provided between a high potential line and a low potential line and selects and outputs a potential of any one of the high potential line and the low potential line in accordance with a second control signal; and a post-stage control unit causing the connection switching unit to connect the control line and the output line when the pre-stage control unit outputs a voltage higher than a predetermined threshold value.
