    • First and second current sources are turned ON/OFF according to display data. A first input transistor has a source connected to a first potential, a drain connected to a second potential via the first current source, and a gate, the drain and the gate being coupled together. A second input transistor has a source connected to the first potential, a drain connected to the second potential via the second current source, and a gate which receives a gate voltage of the first input transistor. A first output transistor has a source connected to the first potential, a drain, and a gate receiving the drain voltage of the second input transistor. A second output transistor has a source connected to the second potential, a drain connected to the drain of the first output transistor, and a gate which receives a control signal corresponding to the display data.
