Abstract

In one aspect, a transparent laminate, including a transparent material layer, a transparent high-elasticity layer laminated on both sides of the transparent material layer and having Young'"'"'s modulus of less than or equal to about 10 MPa, and a transparent high-hardness layer sequentially laminated on the transparent high-elasticity layer that is laminated on both sides of the transparent material layer and having a surface hardness of greater than or equal to a pencil hardness of about 6 H is provided.

Claims

1. A transparent laminate, comprising:

a transparent material layer;

a transparent high-elasticity layer laminated on both sides of the transparent material layer, wherein said transparent high-elasticity layer has a Young'"'"'s modulus of less than or equal to about 10 MPa; and

a transparent high-hardness layer, wherein said transparent high-hardness layer is formed on or directly on the transparent high-elasticity layer by sequentially laminating the transparent high-elasticity layer that is laminated on both sides and wherein said transparent high-hardness layer has a surface hardness of greater than or equal to a pencil hardness of about 6 H.

2. The transparent laminate of claim 1, wherein the transparent laminate is used for a vehicle or a window.

3. A window panel for a display device, comprising:

a transparent material layer;

a transparent high-elasticity layer laminated on both sides of the transparent material layer wherein said transparent high-elasticity layer has a Young'"'"'s modulus of less than or equal to about 10 MPa; and

a transparent high-hardness layer, wherein said transparent high-hardness layer is formed on or directly on the transparent high-elasticity layer by sequentially laminating the transparent high-elasticity layer that is laminated on both sides and wherein said transparent high-hardness layer has a surface hardness of greater than or equal to a pencil hardness of about 6 H.

4. The window panel of claim 3, wherein the transparent material layer has a single layer structure of an organic material layer or an inorganic material layer;

a laminating structure where a plurality of organic material layers, a plurality of inorganic material layer, or a combination of an organic material layer and an inorganic material layer are in a laminated configuration.

5. The window panel of claim 3, wherein the transparent material layer has a Young'"'"'s modulus of greater than or equal to about 1 GPa.

6. The window panel of claim 3, wherein the transparent material layer has a thickness of about 10 μ
