Abstract
A display apparatus includes a blue light blocking layer to block a blue light which is not converted by a color conversion layer, and a reflection preventing layer over the blue light blocking layer to prevent reflection of external light incident thereon.
Claims14
A display apparatus, comprising:
- a panel;
- and
- a quantum dot color filter on the panel,
- wherein the quantum dot color filter includes:
- a first color conversion layer in a first pixel area and including a plurality of quantum dots to convert incident light into a first color light;
- a second color conversion layer in a second pixel area and including a plurality of quantum dots to convert incident light into a second color light;
- a blue light blocking layer including a first blue light blocking portion over the first color conversion layer to block emission of a blue light of the incident light which is not converted by the first color conversion layer, and a second blue light blocking portion over the second color conversion layer to block emission of the blue light of the incident light which is not converted by the second color conversion layer;
- a layer including a first portion over the first color conversion layer to prevent reflection of external light incident thereon and to transmit the first color light from the first color conversion layer therethrough, and a second portion over the second color conversion layer to prevent reflection of external light incident thereon and to transmit the second color light from the second color conversion layer therethrough, the first portion being spaced apart from the second portion;
- and
- a partition comprising a black matrix and disposed between the first color conversion layer and the second color conversion layer, the first color conversion layer and the second color conversion layer being spaced apart from one another.

A display apparatus, comprising:
- a panel;
- a quantum dot color filter on the panel;
- and
- a substrate on the quantum dot color filter, wherein
- the quantum dot color filter includes:
- a first color conversion layer in a first pixel area and including a plurality of quantum dots to convert incident light into a first color light;
- a second color conversion layer in a second pixel area and including a plurality of quantum dots to convert incident light into a second color light;
- a blue light blocking layer including a first blue light blocking portion over the first color conversion layer to block emission of a blue light of the incident light which is not converted by the first color conversion layer, and a second blue light blocking portion over the second color conversion layer to block emission of the blue light of the incident light which is not converted by the second color conversion layer;
- a layer including a first portion arranged over a center of the first color conversion layer and between the substrate and the first color conversion layer and having stacked layers that have different refractive indices from one another, and a second portion arranged over a center of the second color conversion layer and between the substrate and the second color conversion layer and having stacked layers that have different refractive indices from one another, the first portion being spaced apart from the second portion;
- and
- a partition disposed between the first color conversion layer and the second color conversion layer, the first color conversion layer and the second color conversion layer being spaced apart from one another.
