ABSTRACT:
A method of fabricating an organic EL display panel accomplishes pixelation without using a shadow mask, and without exposing active EL elements to solvents from photoresist, or developing and stripping solutions. A first electrode layer and an insulating layer are formed on a transparent substrate. Portions of the insulating layer are removed at predetermined regions using at least one laser beam. An organic function layer and a second electrode layer are then formed on the predetermined regions. The first electrode layer, the organic layer and the second electrode layer form a sub-pixel. Additional sub-pixels are formed using the same method.
