摘要： A display device includes a display area including a first light-emitting area and a second light-emitting area; a peripheral area adjacent to the display area; pixels which emit incident light; an encapsulation layer covering the pixels; a first color-converting pattern corresponding to the first light-emitting area and having a refractivity; a transmission pattern corresponding to the second light-emitting area and through which the incident light is transmitted; a low refractivity layer is in the display area and facing the encapsulation layer with each of the first color-converting pattern and the transmission pattern therebetween, the low refractivity layer including: a resin and a hollow particle which define a refractivity lower than the refractivity of the first color-converting pattern; and a first dam structure in the peripheral area and spaced apart from the display area, the first dam structure and the transmission pattern being portions of a same material 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.
