Patent ID: 7688289

Claim:
An organic EL drive circuit for generating, in response to a predetermined current inputted to an input terminal of a D/A converter circuit constructed with a current mirror circuit, drive currents to be outputted to terminal pins of the organic EL display panel or a current, on which the drive currents are generated, by converting digital display data into analog signal by the D/A converter circuit, comprising: first transistor provided between an input side transistor of the current mirror circuit and the input terminal: a second transistor provided between an output side transistor of the current mirror circuit and an output terminal; and a third transistor provided between the output terminal and a power source line, wherein proof voltages of the input side transistor, the output side transistor and the third transistor are lower than proof voltage of the first and second transistors and; wherein the first transistor and the second transistor are biased such that a connecting point of the input side transistor and the first transistor and a connecting point of the output side transistor and the second transistor become substantially equal potentials.
