A first input terminal and a second input terminal of an organic EL drive circuit IC are arranged on both sides of the organic EL drive circuit IC, which are contiguous to sides of a plurality of IC's having identical circuit constructions to the organic EL drive circuit IC and arranged contiguously to the organic EL drive circuit IC, and a first output terminal and a second output terminal of the organic EL drive circuit IC are provided similarly. When a plurality of IC's are arranged along a column line of an organic EL display panel, it is possible to send a reference current generated by one of the IC or a current corresponding to the reference current to other IC's arranged on left or right sides of the one IC and the other IC's can receive the current sent from the first or second output terminal of the one IC through first or second input terminals of the other IC's, which are provided on sides of the other IC's adjacent to the one IC, and use the currents as reference currents thereof by reference current selector circuits thereof.
