Abstract
A protective window includes a flexible base film and a hard coating layer disposed on the flexible base film. The hard coating layer includes a silicone leveling agent and an inorganic antistatic agent. The coating layer includes an upper area and a lower area disposed between the upper area and the flexible base film, and a density of the inorganic antistatic agent in the lower area is greater than a density of the inorganic antistatic agent in the upper area.
Claims19
A protective window comprising:
- a flexible base film including polyimide;
- a hard coating layer disposed on the flexible base film;
- and
- an interfacial layer between the hard coating layer and the flexible base film,
- wherein the hard coating layer comprises a silicone leveling agent and an inorganic antistatic agent,
- wherein the hard coating layer comprises an upper area, and a lower area disposed between the upper area and the flexible base film, and a density of the inorganic antistatic agent in the upper area is greater than a density of the inorganic antistatic agent in the lower area,
- wherein the interfacial layer includes polyimide and an inorganic antistatic agent including a same material as the inorganic antistatic agent of the hard coating layer.
A display device comprising:
- a base substrate;
- a light-emitting element array disposed on the base substrate;
- an encapsulation layer covering the light-emitting element array;
- and
- a protective window disposed on the encapsulation layer,
- wherein the protective window comprises:
- a flexible base film including polyimide;
- a hard coating layer disposed on the flexible base film;
- and
- an interfacial layer between the hard coating layer and the flexible base film,
- wherein the hard coating layer comprises a silicone leveling agent and an inorganic antistatic agent,
- wherein the hard coating layer comprises an upper area and a lower area disposed between the upper area and the flexible base film, and a density of the inorganic antistatic agent in the upper area is greater than a density of the inorganic antistatic agent in the lower area,
- wherein the interfacial layer includes polyimide and an inorganic antistatic agent including a same material as the inorganic antistatic agent of the hard coating layer.
