The present invention relates to a thermosetting composition, an optical member formed therefrom, and a display apparatus, the composition comprising a thermosetting resin, gas-containing particles and a monomer or an oligomer having two or more thermosetting functional groups, thereby having optical effects such as a low refractive index of 1.40 or less on light with a wavelength of 450 nm, a high light transmittance and a low haze. La présente invention concerne une composition thermodurcissable, un élément optique formé à partir de cette dernière et un appareil d'affichage, la composition comprenant une résine thermodurcissable, des particules contenant un gaz ainsi qu'un monomère ou un oligomère ayant deux groupes fonctionnels thermodurcissables ou plus, présentant ainsi des effets optiques tels qu'un indice de réfraction faible inférieur ou égal à 1,40 de la lumière à une longueur d'onde de 450 nm, un facteur de transmission de la lumière élevé et un trouble faible. 본 발명은 열경화성 조성물, 이로부터 형성된 광학 부재 및 표시 장치에 관한 것으로, 열경화성 레진, 기체함유입자 및 2개 이상의 열경화성 작용기를 갖는 단량체 또는 올리고머를 포함하여, 450 nm 파장의 빛에 대하여 1.40 이하의 저굴절률, 높은 광투과성 및 낮은 헤이즈와 같은 광학 효과를 가진다.
