Abstract

A method of fabricating a display device includes: preparing a substrate including emission areas and a non-emission area between the emission areas; forming a bank on the non-emission area to a first height; forming light conversion patterns on the emission areas to a height equal to or less than the first height; polishing a surface of a light conversion layer including the bank and the light conversion patterns so that the surface of the light conversion layer is flat; and forming a filler layer on a surface of the substrate on which the light conversion layer is provided. The polishing of the light conversion layer includes planarizing the surface of the light conversion layer so that the bank and the light conversion patterns have a second height through chemical mechanical polishing utilizing a metallic slurry.
