▎ 摘　　要

NOVELTY - The substrate has pixels composed of a set of sub-pixels of different colors. A laminated structure is provided with a single quantum dot corresponding to the sub-pixel. The laminated structure is composed of alternately laminated sheet-like graphene-containing layer of a single quantum dot layer. A bottom layer and a top layer of the laminated structure are sheet-shaped graphite layer. Excitation of light is emitted corresponding to the sub-pixel color of monochromatic light. USE - Color film substrate. ADVANTAGE - The substrate can make single quantum dot evenly dispersed to the adjacent sheet-like graphene-containing layer to prevent the accumulation of the single quantum dot so as to improve the quantum excitation light. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a color film substrate.
