1. An organic light emitting device, comprising:
- a bottom electrode;
a patterned first organic layer disposed over the bottom electrode, comprising a first region capable of emitting a first spectrum of light;
a second organic layer disposed over and in physical contact with the first organic layer, the second organic layer being disposed over the bottom electrode, the second organic layer being capable of emitting a second spectrum of light; and
a top electrode disposed over the second organic layer.

Abstract
An organic light emitting device that may have mixed organic layers is provided. A method of fabricating such an organic light emitting device is provided. A first organic material is solution deposited to form a patterned organic layer over a first electrode. A second organic material is deposited, by means other than solution processing, on and in physical contact with the first organic layer to form a second organic layer. The second organic layer forms a blanket layer over the first organic layer. A second electrode is then deposited over the second organic layer.
