Abstract

See full text

The present invention relates to a light emitting device with at least two active areas and a more robust method of manufacturing such a device, wherein a first electrode layer (20) is deposited through a mask overcoating an active material (10). A second active material (30) is deposited through another mask in such a way that an area which covers and extends beyond the first electrode layer (20) is overcoated with the organic material. Then, a second electrode layer (40) is coated through a mask such that it overcoats the whole second active material (30).
