Abstract
An organic electroluminescence device is provided, which comprises: a lighting region, a wiring region, a bonding region and a wiring extending region (300), the lighting region comprises an anode, an organic functional layer, a cathode; the wiring region comprises wirings connecting the anode and cathode with a driving chip or a circuit board; the bonding region is a region in which the wirings connect with the driving chip or the circuit board; the ends of the wirings locate in the wiring extending region, the wirings in the wiring extending region are parallel with the wirings in the wiring region or form an angle with the wirings in the wiring region. A method for testing the organic electroluminescence device is also provided. With improving the wiring arrangement of the organic electroluminescence device, it is easier and more accurate to press bond a conductive adhesive tape and the wirings, and, the row wirings and the column wirings are protected from being shorted during screen testing.
