Patent ID: 8836337

Claim:
An organic electroluminescent device, comprising: a lighting region, a wiring region, a bonding region, and a wiring extending region formed on a substrate; the lighting region comprises an anode, an organic functional layer, and a cathode; the wiring region comprises wirings connecting the anode and the cathode with a driving chip or a circuit board; the bonding region is a region in which the wirings are bonded with the driving chip or the circuit board; the wiring extending region is a region in which ends of the wirings are located; wherein a portion between the lighting region and the bonding region constitutes the wiring region; wherein a portion between the bonding region and the lower edge of the substrate constitutes the wiring extending region; wherein the wirings in the wiring region, the bonding region and the wiring extending region, as a whole, are formed on the substrate by a photolithography process; and wherein, an angle formed by the wirings in the wiring extending region and the wirings in the wiring region is larger than 0° and less than 90°.
