Abstract

A light emitting device (100) is provided, comprising a substrate (101), a first electrically conductive layer (102), a light emitting layer (103), and a second electrically conductive layer (104). The light emitting device (100) further comprises at least one metal shunt (105) which is in electrical contact with said first electrically conductive layer (102). The at least one metal shunt (105) is isolated from said second electrically conductive layer (104) at least by means of a dielectric oxide layer (106). The present invention allows for the use of electrically insulating material between one or more metal shunts and a cathode layer without reducing the effective pixel area of the device.
