A light emitting element driving circuit for driving a light emitting element in accordance with a differential data signal for causing the light emitting element to turn on or turn off is provided. The circuit includes a first transistor, a first constant current source connected to a drain and gate of the first transistor and configured to supply a constant current through the drain and source of the first transistor, a second transistor configured to supply a certain current, and a control circuit configured to electrically connect or disconnect the gate of the first transistor to or from a gate of the second transistor via a first resistor. The control circuit may supply, to the gate of the second transistor, an intermediate potential in accordance with the other of the differential data signals, while the gate of the first transistor is electrically disconnected from the gate of the second transistor.
