Abstract
An optical member including a base substrate, a quantum dot layer disposed on the base substrate and having a first top surface including a lower wrinkle, the quantum dot layer including a medium layer and a plurality of quantum dots dispersed in the medium layer, a lower barrier layer disposed between the base substrate and the quantum dot layer, and an upper barrier layer covering the quantum dot layer, in which the upper barrier layer has a second top surface with an upper wrinkle corresponding to the lower wrinkle of the quantum dot layer.
Claims24
An optical member, comprising:
- a base substrate;
- a quantum dot layer disposed on the base substrate and having a first top surface including a lower wrinkle, the quantum dot layer comprising a medium layer and a plurality of quantum dots dispersed in the medium layer;
- a lower barrier layer disposed between the base substrate and the quantum dot layer and having a substantially flat top surface;
- and
- an upper barrier layer covering the first top surface of the quantum dot layer,
- wherein the upper barrier layer has a second top surface with an upper wrinkle corresponding to the lower wrinkle of the quantum dot layer.
A display apparatus, comprising:
- a light source configured to emit light;
- an optical member having an incidence surface facing the light source;
- and
- a display panel disposed on the optical member and comprising a plurality of pixels,
- wherein the optical member comprises:
- a base substrate including a top surface facing the display panel, a bottom surface opposite to the top surface, and a plurality of side surfaces connecting the top surface to the bottom surface, at least one of the side surfaces comprising the incidence surface;
- a lower barrier layer disposed on the base substrate, the lower barrier layer having a flat top surface;
- an upper barrier layer disposed on the lower barrier layer, the upper barrier layer having a wrinkled top surface with a plurality of wrinkles formed thereon;
- and
- a quantum dot layer disposed between the lower barrier layer and the upper barrier layer, the quantum dot layer including a medium layer and a plurality of quantum dots dispersed in the medium layer,
- wherein the wrinkles have a curvilinear shape, when viewed in a plan view.
