Abstract: Disclosed are an optical member and a display device including the same. The optical member includes a receiving member; a host in the receiving member; and a plurality of wavelength conversion particles distributed in the host. The receiving member includes a light incident part having a first refractive index; and a light exit part having a second refractive index different from the first refractive index. The optical member improves the optical characteristics by adjusting the refractive indexes of the light incident part and the light exit part.
