The invention discloses an antibacterial decoration plate having an LED lamp belt. The antibacterial decoration plate comprises a plate body, wherein the upper side of the plate body is provided with an LED lamp installation groove, an LED lamp belt is arranged in the LED lamp installation groove, the plate body comprises a substrate and an antibacterial layer arranged the substrate, and the antibacterial layer is a mixture layer formed by mixing a TiO2 photocatalyst material, nanometer silver and a formaldehyde decomposition effective component. According to the present invention, the antibacterial decoration plate has advantages of excellent durability, antibacterial property, mildew resistance, high strength, sound absorption, sound insulation, strong compactness, good permeability, and low cost; the nanometer silver has characteristics of stable performance and difficult volatilization, the nano-scale silver continuously and stably releases silver ions through ionization, and the released silver ions enter the bacterial body so as to maintain the long-term anti-bacterial function; and the TiO2 photocatalyst material produces the catalysis reaction similar to photosynthesis under sunlight or visible light irradiation so as to form the hydrogen oxygen free radicals and the reactive oxygen having extremely strong oxidation ability.
