Abstract

An electronic device includes a window having a modulus of about 55 GPa to about 80 GPa, an panel including an electronic element, and a plurality of adhesive layers between the window and the panel, wherein a sum of thicknesses of the adhesive layers is less than about 200 μm, wherein the adhesive layers include a first adhesive layer contacting the panel, and a second adhesive layer contacting the window, and wherein a thickness of the first adhesive layer is equal to or less than about ½ of the sum of the thicknesses of the adhesive layers.

First claim

What is claimed is:

1 . An electronic device comprising:
a window; a panel comprising an electronic element; and a plurality of adhesive layers between the window and the panel, wherein a sum of thicknesses of the adhesive layers is less than about 200 μm.

2 . The electronic device of claim 1 , wherein the sum of the thicknesses of the adhesive layers is equal to or greater than about 75 μm.

3 . The electronic device of claim 1 , wherein the adhesive layers comprise:
a first adhesive layer on the panel; and a second adhesive layer on the window, wherein a thickness of the first adhesive layer is equal to or less than about ½ of the sum of the thicknesses of the adhesive layers.

4 . The electronic device of claim 3 , further comprising:
a first additional member between the panel and the window; and a second additional member between the first additional member and the window.

5 . The electronic device of claim 4 ,
wherein the adhesive layers further comprise a third adhesive layer between the first additional member and the second additional member, and wherein the sum of the thicknesses of the adhesive layers is a sum of thicknesses of the first, second, and third adhesive layers.

6 . The electronic device of claim 4 ,
wherein the first additional member is one of an optical member and an input sensing member, and wherein the second additional member is the other of the optical member and the input sensing member.

7 . The electronic device of claim 4 , wherein the first additional member and the second additional member comprise at least one of an optical member or an input sensing member.

8 . The electronic device of claim 3 , wherein the first adhesive layer contacts the panel, and the second adhesive layer contacts the window.

9 . The electronic device of claim 1 , wherein the window has a modulus of about 55 GPa to about 85 GPa.

10 . An electronic device comprising:
a window; a panel comprising an electronic element; and a plurality of adhesive layers between the window and the panel, wherein the adhesive layers comprise:
a first adhesive layer on the panel;
a second adhesive layer on the window; and
a third adhesive layer between the first adhesive layer and the second adhesive layer, and
wherein a thickness of the first adhesive layer is equal to or less than about ½ of a sum of thicknesses of the adhesive layers.

11 . The electronic device of claim 10 , further comprising:
a first additional member and a second additional member between the panel and the window, each of the first additional member and the second additional member comprising a transparent resin, wherein the third adhesive layer is between the first additional member and the second additional member.

12 . The electronic device of claim 10 , wherein the sum of the thicknesses of the adhesive layers is less than about 200 μm, and is equal to or greater than about 75 μm.

13 . The electronic device of claim 10 , further comprising:
a protective panel on the window; and an upper adhesive layer between the protective panel and the window to couple the protective panel and the window to each other.

14 . The electronic device of claim 10 , wherein the window comprises a thin film glass having a modulus of about 55 GPa to about 85 GPa.

15 . The electronic device of claim 10 , wherein the window has a thickness of about 80 μm or less.

16 . The electronic device of claim 10 , further comprising a supplementary member between the second adhesive layer and the third adhesive layer.

17 . The electronic device of claim 16 , wherein the supplementary member comprises a transparent resin.

18 . The electronic device of claim 10 , wherein the panel comprises:
a base substrate having modulus of about 1 GPa to about 10 GPa; a pixel layer on a front surface of the base substrate and comprising a plurality of pixels; and an encapsulation layer covering the pixel layer, and wherein the panel is configured to display an image on a front surface thereof.

19 . The electronic device of claim 10 , wherein a folding axis is defined on a back surface of the panel,
wherein the folding axis is parallel to the back surface of the panel, and wherein the panel and the window are foldable along the folding axis.

20 . An electronic device comprising:
a panel foldable along a folding axis extending in one direction; a window on a front surface of the panel and having a modulus of about 55 GPa to about 85 GPa; a first additional member and a second additional member between the panel and the window; and a plurality of adhesive layers between the window and the panel, and comprising:
a first adhesive layer on the panel;
a second adhesive layer between the first adhesive layer and the window; and
a third adhesive layer between the first additional member and the second additional member,
wherein a sum of thicknesses of the adhesive layers is between about 75 um and about 200 μm, and wherein a thickness of the first adhesive layer is equal to or less than about ½ of the sum of the thicknesses of the adhesive layers.
