Abstract:
A method for manufacturing an organic electroluminescent display, comprising the steps of:forming a plurality of first display electrodes arranged in parallel on a substantially transparent substrate; forming an insulating layer on the transparent substrate, the insulating layer including a plurality of slots perpendicular to the first display electrodes for exposing the first display electrodes; forming insulating ramparts on the exposed first display electrodes, the portion of the insulating ramparts away from the substrate further forming overhangs, and the portion of the insulating ramparts proximate to the substrate having sufficiently high cross-linking for increasing the adhesion between the insulating ramparts and the first display electrodes; partially removing the insulating layer through the masking effect of the overhangs for exposing the first display electrode; forming an organic electroluminescent material on the exposed first display electrodes; and forming a plurality of second display electrodes on the organic electroluminescent material.
