Abstract:
An organic EL element drive circuit including a current mirror circuit having an input side transistor supplied with a predetermined drive current and a plurality of output side parallel transistors, from which drive currents to be supplied to terminal pins of an organic EL panel are derived, comprising:a current output circuit for generating a current having a first value in response to an output current of one of said output side transistors; and a current generator circuit for generating said predetermined drive current in response to a current having a second value outputted by another organic EL element drive circuit preceding to said organic EL element drive circuit and having a current output circuit and a current mirror circuit substantially the same as said current output circuit and said current mirror circuit of said organic EL element drive circuit, the current having the second value being outputted from said current output circuit of said another organic EL element drive circuit.
