ABSTRACT:
Each of a plurality of driver circuits includes a first 3-terminal switch element, a second 3-terminal switch element, and a 3-terminal light emitting element driven by the first 3-terminal switch element. The first 3-terminal switch element in a first circuit of adjacent driver circuits is driven by one of first and second clocks and the first 3-terminal switch element in a second circuit of the adjacent driver circuits is driven by the other of the first and second clocks. The second 3-terminal switch element in the first circuit supplies a signal to the second driver circuit, the signal representing an operational state of the first circuit. The second 3-terminal switch element in the first circuit includes a control electrode to which a third clock is supplied. The second 3-terminal switch element in the second circuit includes a control electrode to which a fourth clock is supplied.
