摘要： Provided are a wavelength conversion element and a display device comprising the same. A color conversion element comprises: a wavelength conversion layer (320); one or more low refractive layers (400a, 400b) which are disposed on and/or under the wavelength conversion layer and have a lower refractive index than the wavelength conversion layer; and one or more capping layers (CL) which are disposed between the wavelength conversion layer and the low refractive layers and/or on a surface opposite to a surface of each of the low refractive layers which faces the wavelength conversion layer.

摘要： An optical film for a display device, includes: a first refractive layer having an upper surface and a lower surface including first projections and second projections extending away from the lower surface in a first direction, the second projections having different heights than the first projections, the first projections having lateral sides with different angles of inclination that decrease in the first direction; and a second refractive layer disposed directly on the upper surface of the first refractive layer, the second refractive layer having a refractive index different from that of the first refractive layer.
