Abstract
An organic light emitting device (and a method for producing the device) includes a multilayered structure with a substrate layer providing a first electrode layer, a second electrode layer and at least one layer of light emitting organic material between the first and second electrode layers. The second electrode layer includes at least two separate layers, a layer of a semi-transparent metal electrode and a layer of light transparent lateral conductor, is deposited onto the layer of light emitting organic material such as depositing the semi-transparent metal electrode layer onto the layer of light emitting organic material, depositing subsequently at least one protection layer thereupon and depositing the light transparent lateral conductor layer onto the protection layer.

A method for producing an organic light emitting device including a multilayered structure with a substrate layer providing a first electrode layer, a second electrode layer including two separate layers comprising a layer of a semi-transparent metal electrode and a layer of light transparent lateral conductor, and at least one layer of light emitting organic material between said first and second electrode layers, said method comprising:
- depositing said layer of said semi-transparent metal electrode onto said layer of light emitting organic material;
- depositing subsequently at least one protection layer onto said layer of semi-transparent metal electrode;
- and
- depositing said layer of light transparent lateral conductor onto said at least one protection layer.
A method for producing an organic light emitting device (OLED), comprising:
- forming a first electrode layer, a second electrode layer over said first electrode and including a layer of a semi-transparent metal electrode and a layer of light transparent lateral conductor, and at least one layer of light emitting organic material between said first and second electrode layers,
- wherein said forming comprises:
- depositing said layer of said semi-transparent metal electrode over said layer of light emitting organic material;
- depositing subsequently at least one protection layer over said layer of semi-transparent metal electrode;
- and
- depositing said layer of light transparent lateral conductor over said at least one protection layer.
