    • The present invention relates to a light emitting device (100) comprising: a substrate (102); a light emitting diode structure (106) arranged on the substrate (102), the diode structure (106) comprising a first semiconducting layer (108), an active region (110) and a second semiconducting layer (112), wherein a light output surface of the diode structure comprises a plurality of protruding surface structures (104) each having a peak height, a sidewall slope (122) and orientation in relation to the substrate, the plurality of protruding structures (104) comprising a first set and a second set of protruding surface structures, the first set and second set of protruding surface structures differing by at least one of the peak height, sidewall slope and orientation in relation to the substrate. The invention also relates to a method for manufacturing a light emitting device where the protruding surface structures are formed by imprint lithography to form a three-dimensional pattern and subsequent etching.
