The present invention relates to a coating composition, which includes:n (A) a polysiloxane resin, including a unit derived from a siloxane monomer, a siloxane oligomer, or a combination thereof; and (B) inorganic particles, including first SiO 2 particles with a particle size ranging from 15 nm to 100 nm, and second SiO 2 particles with a particle size ranging from 3 nm to <15 nm. nn The present invention further relates to a coating layer for enhancing light transmittance that is formed by the coating composition. According to the present invention, by using at least two types of inorganic particles with specific particle sizes to form a geometric stack, the space of pores can be increased, and therefore, the porosity of the coating layer can be increased, thereby reducing the optical refractive index of the coating layer and achieving an effect of enhancing light transmittance. |
