PURPOSE:To reduce the necessary number of electrodes, to enhance resolution, to reduce its cost and to raise reliability by providing a light emitting element block including a plurality of light emitting elements, a plurality of first electrodes for supplying first signals, and a plurality of second electrodes for supplying second signals. CONSTITUTION:Light emitting element blocks B including a plurality of light emitting elements T for emitting lights when first and second signals are simultaneously supplied, a plurality of electrodes A for supplying the first signals to the elements T in the block B to be provided in the blocks B, and a plurality of second electrodes G for supplying the second signals to the elements T to be provided at the elements T corresponding to the blocks B are provided. Thus, the number of electrodes can be reduced, and since the arraying pitch of the elements can be reduced, its resolution can be enhanced, its cost can be reduced, and high reliability is performed. |
