摘要： A low refractive layer includes a plurality of hollow inorganic particles and a matrix between the hollow inorganic particles, and capable of exhibiting a good refractive index and improved durability by enhancing the weight ratio of the hollow inorganic particles to the matrix. An electronic device according to an embodiment of the inventive concept including the low refractive layer may exhibit improved reliability and good display quality.

摘要： Provided is an optical member. The optical member includes a color filter member including quantum dots and a low-refractive index layer below the color filter member and including a first hollow particle and a second hollow particle. The first hollow particle may have a particle size different from a particle size of the second hollow particle.

摘要： An electronic device includes a light source member configured to provide a first light, a color conversion member disposed on the light source member and including a first conversion material that converts the first light into a second light and a second conversion material that converts the first light into a third light, and a low-refractive index layer disposed on the light source member and disposed on at least one of upper and lower portions of the color conversion member. The low-refractive index layer includes a matrix part, a plurality of hollow inorganic particles dispersed in the matrix part, and a plurality of void parts defined by the matrix part.
