Patent ID: 7525247

Claim:
A substrate for organic EL display devices, which comprises a plurality of structures, each of the structures having anode strips, organic EL layers and cathode strips and being formed in a rectangular shape, wherein wires for connection with the cathode strips are connected to a first side and a second side of an organic EL device, and wires for connection with the anode strips are connected to a third side of the organic EL device in each of the structures, and wherein anode-mounting terminals and cathode-mounting terminals, which are connected to a driving circuit, are formed in a portion in the vicinity of the third side of each of the structures; each of the structures comprising anode-common wires for aging formed so as to pass in the vicinity of the first side; each of the structures comprising cathode-common wires for aging formed so as to pass in the vicinity of the second side; each of the structures comprising a connecting member for the anode strips formed in the vicinity of a fourth side, the connecting member for the anode strips being electrically connected to anode strips of another organic EL device adjacent the fourth side; each of the structures comprising a connecting member for the cathode strips formed in the vicinity of the connecting member for the anode strips, the connecting member for the cathode strips being electrically connected to cathode strips of said another organic EL device; and each of the structures comprising a cathode-lead wire for aging formed so as to pass on the structure with said another organic EL device formed thereon, the cathode-lead wire for aging connecting between the cathode-common wires for aging and the connecting member for the anode strips.
