Abstract

Disclosed is display device including a display panel; a window disposed on the display panel; and an adhesive layer positioned between the display panel and the window, wherein the adhesive layer includes a polymer resin and a woven fiber.

First claim

What is claimed is:

1. A display device, comprising:
a display panel;
a window disposed on the display panel; and
an adhesive layer disposed between the display panel and the window,
wherein the adhesive layer comprises a polymer resin and a woven fiber,
wherein the polymer resin comprises a first resin disposed directly on a lower surface of the woven fiber and a second resin disposed directly on an upper surface of the woven fiber,
wherein the adhesive layer has a tensile modulus of about 0.001 to about 1 GPa.

2. The display device of claim 1 , wherein the woven fiber comprises at least one of a glass fiber, a carbon fiber, a boron fiber, an aramid fiber, a polyester fiber, a ceramic fiber, asbestos, and a cellulose-based fiber.

3. The display device of claim 1 , wherein the woven fiber has a refractive index of about 1.4 to about 1.7.

4. The display device of claim 1 , wherein the woven fiber has an average diameter of about 10 to about 90 um.

5. The display device of claim 1 , wherein the adhesive layer further comprises multiple layers of woven fibers.

6. The display device of claim 1 , wherein the woven fiber constitutes about 20 to about 90 wt % of the adhesive layer.

7. The display device of claim 1 , wherein the polymer resin comprises at least one of an acryl-based resin, an epoxy-based resin, a urethane-based resin, a silicon-based resin, and an imide-based resin.

8. The display device of claim 1 , wherein the polymer resin has a refractive index of about 1.4 to about 1.7.

9. The display device of claim 1 , wherein the first resin and the second resin have the same adhesive strength.

10. The display device of claim 1 , wherein the first resin and the second resin have different adhesive strengths from each other.

11. The display device of claim 1 , wherein the adhesive layer has shear modulus of about 100 to about 1500 MPa.

12. The display device of claim 1 , wherein the display device is a liquid crystal display (LCD), an organic light emitting diode (OLED) display, a plasma display, an electric field effect display device, or an electrophoresis display device.
