摘要： An optical filter includes a substrate, a filter layer on the substrate and including color filters, and a light-converting layer over the filter layer and including light-converting portions respectively corresponding to the color filters. A low refractive index layer is between the filter layer and the light-converting layer and has a refractive index less than a refractive index of the light-converting layer. A first capping layer is between the low refractive index layer and the light-converting layer and has a refractive index ranging between the refractive index of the light-converting layer and the refractive index of the low refractive index layer.

摘要： A display panel includes an upper substrate to which external light is incident, a sealing member which is in a non-display area and couples the upper substrate to a lower display substrate. The upper display substrate includes: a base substrate; a light shielding layer and filter layer each corresponding to the non-display area and absorbing a portion of external light which is transmitted through the base substrate at the non-display area, the filter layer and the light shielding layer having different colors from each other. In a first non-display area of the base substrate which corresponds to the sealing member, only one among the filter layer and the light shielding layer is disposed. In a second non-display area of the base substrate which is adjacent to the first non-display area, both the filter layer and the light shielding layer are disposed.
