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.

Abstract: There is provided a display device. The display device includes a first substrate, a second substrate that faces the first substrate, and a liquid crystal layer disposed between the first substrate and the second substrate. One of the first substrate and the second substrate includes a base substrate and a light blocking pattern disposed on a surface that faces the other surface of both surfaces of the base substrate, the light blocking pattern exposing a part of the base substrate. The light blocking pattern includes a semi-transmission reflective layer a disposed on the base substrate, a phase matching layer disposed on the semi-transmission reflective layer, and a reflective metal layer disposed on the phase matching layer. The phase matching layer and the reflective metal layer include materials having substantially the same etching rate.
