▎ 摘　　要

NOVELTY - Dissimilar coated steel plate comprises grater, heat-insulating coating layer formed in first region of first surface of steel sheet, and heat dissipation coating layer formed in second region of first surface of steel sheet. The heat dissipation coating layer includes graphene. The graphene is concentrated on interface between steel sheet and heat dissipation coating layer or on surface of heat dissipation coating layer. The heat-dissipating coating layer is formed on second surface opposite to the first surface of steel sheet. The area of the first region is greater than area of the second region. The heat-dissipating coating layer comprises 0.01-20 wt.% graphene. The heat dissipation coating layer has average thickness of 0.5-5.0 nu m. USE - The dissimilar coated steel plate is useful in display device i.e. plasma display device, liquid crystal display, light emitting diode, and organic light emitting diodes. ADVANTAGE - The dissimilar coated steel plate: lowers power consumption; has long lifespan, and excellent brightness and viewing angle and long viewing distance; has high expressive power, excellent formability, workability, weldability, corrosion resistance and paintability; prevents damage due to heat and has excellent physical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for display device. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of steel plate (Drawing includes non-English language text).
