Low-refractivity optical clear resin

Abstract

A low-refractivity optical clear resin is disclosed. The low-refractivity optical clear resin comprises a polysiloxane composition and an organic solvent composition, wherein the polysiloxane composition comprises a polysiloxane and a hydroxyalkylsilane monomer, and the organic solvent composition comprises a high boiling point solvent with a boiling point more than 180° C. and a low boiling point solvent with a boiling point less than 150° C.; wherein the used amount of the organic solvent composition is 50 to 120 parts by weight per 10 parts by weight of the polysiloxane composition. The present low-refractivity optical clear resin can be used on the micro light emitting diode (micro-LED) display devices to enhance the light extracting efficiency thereof, and provide excellent optical properties on an adequate coating thickness.
