1. 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°

Abstract
An organic light emitting device includes a substrate having a plurality of pixels, each pixel comprising a plurality of sub-pixels. Each sub-pixel includes an emission area that has a first electrode, a second electrode and an emitting layer, with the emitting layer of at least one sub-pixel includes a phosphorescence material. In addition to these features, the device includes a scan line to provide scan signal to a corresponding sub-pixel, a data line configured to supply data signal to a corresponding sub-pixel, and a power supply line to provide power to a corresponding sub-pixel. The data line and power supply line have a single-layer structure, and a taper angle of each of the data line and the power supply line lies in a predetermined range.
