Abstract
Provided are display device and method for fabricating the same. According to an aspect of the present disclosure, there is provided a display device comprising: a first substrate; at least one wavelength conversion layer disposed on the first substrate; a capping layer disposed on the wavelength conversion layer and comprising a porous layer; and a first polarizing layer disposed on the capping layer.
Claims17
A display device comprising:
- a first substrate;
- at least one wavelength conversion layer disposed on the first substrate;
- a capping layer disposed on the wavelength conversion layer and comprising a porous layer and a first inorganic layer;
- a planarization layer disposed on the capping layer;
- a black matrix disposed between the capping layer and the first substrate;
- and
- a first polarizing layer disposed on the planarization layer,
- wherein the porous layer is disposed between the wavelength conversion layer and the first inorganic layer,
- wherein the porous layer contacts the wavelength conversion layer and the black matrix, and
- wherein the porous layer has a thermal expansion coefficient larger than the thermal expansion coefficient of the first inorganic layer and smaller than the thermal expansion coefficient of the planarization layer.
