Abstract
A method of manufacturing an electroluminescent device includes forming a first patterned structure in a first pixel through a first opening of a first sacrificial layer; removing the first sacrificial layer; forming a second patterned structure in a second pixel through a second opening of a second sacrificial layer; removing the second sacrificial layer; and removing a first patterned protecting layer from the first patterned structure and a second patterned protecting layer from the second patterned structure to respectively form a first patterned light-emitting layer and a second patterned light-emitting layer.
