Abstract:
A method of fabricating an organic electroluminescent (EL) display panel, comprising:forming a first electrode layer on a transparent substrate;forming an insulating layer having an insulating surface on the first electrode layer;selectively removing portions of the insulating layer at predetermined first regions using at least one laser beam to expose a first set of first sub-pixel electrodes;forming a set of organic function layers on the first set of first sub-pixel electrodes and on remaining portions of the insulating surface, said organic function layers comprising at least one organic EL medium layer; andforming a set of second electrode layers on the organic function layers to form a second set of first sub-pixel electrodes, wherein the first set of first sub-pixel electrodes, the portions of the organic function layers electrically communicating with the first set of first sub-pixel electrodes and the second set of the sub-pixel electrodes and the second set of first sub-pixel electrodes form a first set of first sub-pixels wherein the remaining portions of the insulating layer following selective removal of the predetermined first regions separate a sub-pixel from other sub-pixels.
