Abstract

A dual-mode display including a substrate and a plurality of sub-pixels on the substrate, in which each sub-pixel includes, a reflective device having an optical filter function which reflects different color according to electrical signals applied from outside the display, and an emissive device disposed on the reflective 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.
