Abstract

Provided is a dual-mode display including a substrate and a plurality of sub-pixels on the substrate, in which each sub-pixel includes an emissive device, a color selection reflector disposed on one side of the emissive device, and an optical shutter disposed on another side of the emissive device, wherein the emissive device includes a cathode and an anode, and the cathode and the anode include a carbon-based material including graphene sheets, graphene flakes, and graphene platelets, and a binary or ternary transparent conductive oxide including indium oxide, tin oxide, and zinc oxide.
