Display device including protective window
A display device including a flat area extending in a direction and a bending area having a curvature is provided. The display device includes a panel part including a pixel array and including a first active area located in the flat area and a second active area located in the bending area, a protective window covering the panel part, and a high-refractive member on the panel part in the bending area and including a material having a refractivity greater than a refractivity of the protective window.
1. A display device including a flat area extending in a direction and a bending area having a curvature, the display device comprising:
a panel part including a pixel array and including a first active area located in the flat area and a second active area located in the bending area;
a protective window covering the panel part; and
a high-refractive member on the panel part in the bending area and configured to pass light from the panel part therethrough, the high-refractive member including a material having a refractivity greater than a refractivity of the protective window.
2. The display device of claim 1 , wherein the high-refractive member is between the protective window and the panel part in the bending area.
3. The display device of claim 1 , wherein the high-refractive member is between a first low-refractive layer and a second low-refractive layer of the protective window in the bending area.
4. The display device of claim 1 , wherein the protective window includes glass, and the high-refractive member includes at least one selected from the group consisting of polymethyl methacrylate, polyvinyl alcohol, polyimide, cyclic olefin copolymer, and polycarbonate.
5. The display device of claim 1 , wherein the protective window includes polyimide, and the high-refractive member includes at least one selected from the group consisting of cyclic olefin copolymer and polycarbonate.
6. The display device of claim 1 , wherein the high-refractive member includes a cured acrylic resin.
7. The display device of claim 1 , wherein the high-refractive member includes inorganic nano-particles dispersed in a flexible polymer matrix or in a cured resin.
8. The display device of claim 7 , wherein the inorganic nano-particles include at least one selected from the group consisting of niobium oxide, barium oxide, titanium oxide, zirconium oxide, and tungsten oxide.
9. The display device of claim 1 , wherein the high-refractive member includes a metal oxide layer.
10. The display device of claim 1 , wherein the high-refractive member includes a high-refractive glass including at least 15 wt % of niobium oxide, barium oxide, titanium oxide, zirconium oxide, tungsten oxide, or a combination thereof.
11. The display device of claim 1 , further comprising a light-blocking member that overlaps a non-display area of the panel part in the bending area.
12. The display device of claim 1 , wherein a thickness of the protective window in the bending area is less than a thickness of the protective window in the flat area.
13. The display device of claim 1 , wherein the pixel array includes an organic light-emitting diode.
14. A display device including a flat area extending in a direction and a bending area having a curvature, the display device comprising:
a panel part including a pixel array and including a first active area located in the flat area and a second active area located in the bending area;
a protective window covering the panel part; and
a high-refractive member on the panel part in the bending area and including a material having a refractivity greater than a refractivity of the protective window,
wherein the protective window is between the high-refractive member and the panel part in the bending area.
15. A display device including a flat area extending in a direction and a bending area having a curvature, the display device comprising:
a panel part including a pixel array and including a first active area located in the flat area and a second active area located in the bending area; and
a protective window covering the panel part,
wherein the protective window includes a low-refractive portion located in the flat area and a high-refractive portion located in the bending area and having a refractivity greater than a refractivity of the low-refractive portion.
16. The display device of claim 15 , wherein the protective window includes glass or polyimide.
17. The display device of claim 15 , wherein the high-refractive portion includes at least one selected from the group consisting of polymethyl methacrylate, polyvinyl alcohol, polyimide, cyclic olefin copolymer, and polycarbonate.
18. The display device of claim 15 , wherein the high-refractive portion includes a cured acrylic resin.
19. The display device of claim 15 , wherein the high-refractive portion includes inorganic nano-particles dispersed in a flexible polymer matrix or in a cured resin.
20. The display device of claim 15 , wherein the high-refractive portion includes a high-refractive glass including at least 15 wt % of niobium oxide, barium oxide, titanium oxide, zirconium oxide, tungsten oxide, or a combination thereof.
