摘要： A current drive circuit supplies a driving current to a pixel portion included in a current-driven display panel. A driving current generator includes an output terminal for supplying the driving current. A protective transistor has a drain connected to the pixel portion, a source connected to the output terminal, and a gate to which a first bias voltage is supplied. The first bias voltage has a voltage level lower than or equal to a voltage level obtained by adding the threshold voltage of the protective transistor to the breakdown voltage of the driving current generator.
