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.
