Patent ID: 8519920

Claim:
An organic light emitting device comprising: a substrate having a plurality of pixels, each pixel comprising a plurality of sub-pixels, wherein each sub-pixel includes an emission area, the emission area including a first electrode, a second electrode and an emitting layer; a plurality of scan lines, a scan line configured to provide scan signal to a corresponding sub-pixel; a plurality of data lines, a data line configured to supply data signal to a corresponding sub-pixel; a plurality of power supply lines, a power supply line configured to provide power to a corresponding sub-pixel, wherein the data line and the power supply line have a triple-layer structure with different taper angles formed at respective edge portions abutting on an insulating layer, such that a first layer taper angle of the data line and the power supply line lies substantially between 30° to 60°, a second layer taper angle of the data line and the power supply line, being greater than the second layer taper angle, lies substantially between 70° to 90°.
