Abstract

A display device and a method of manufacturing a display device are provided. A display device includes: a window; a first pattern on a portion of the window; a second pattern on at least a portion of the first pattern and having a higher surface free energy than the first pattern; an adhesive layer on the window, at least a portion of the adhesive layer being on the second pattern to be in contact with a surface of the second pattern; and a display panel on the adhesive layer.

Claims (27)

1. A display device comprising:

a window;

a first pattern over a portion of the window, the first pattern including a lower surface facing the window and an upper surface opposite to the lower surface, the first pattern being a light-shielding pattern which blocks light transmission;

a second pattern over at least an inwardmost portion of the upper surface of the first pattern, the second pattern including a lower surface facing the upper surface of the first pattern and an upper surface opposite to the lower surface of the second pattern;

an adhesive layer over the window, at least a portion of the adhesive layer being over the upper surface of the second pattern; and

a display panel over the adhesive layer,

wherein the at least a portion of the adhesive layer directly contacts a portion of the upper surface of the second pattern, and

wherein the portion of the upper surface of the second pattern which directly contacts the at least a portion of the adhesive layer has a higher surface free energy and/or a higher surface roughness than the upper surface of the first pattern.

2. The display device of claim 1 , wherein the portion of the upper surface of the second pattern has a surface tension of 34 dyne/cm or more.

3. The display device of claim 1 , wherein an edge of the display panel over at least one side protrudes further outward than a corresponding edge of the adhesive layer.

4. The display device of claim 1 , wherein the second pattern completely covers the first pattern.

5. The display device of claim 1 , wherein the adhesive layer comprises a resin cured by irradiation of light.

6. The display device of claim 5 , wherein the light is ultraviolet (UV) light.

7. The display device of claim 1 , further comprising an auxiliary sealing layer covering a side surface of the display panel and a side surface of the adhesive layer.

8. The display device of claim 7 , wherein the auxiliary sealing layer is arranged at corner portions of the display panel and the adhesive layer in a plan view.

9. The display device of claim 7 , wherein each of the adhesive layer and the auxiliary sealing layer comprises a resin cured by irradiation of light.

10. The display device of claim 9 , wherein the resins respectively contained in the adhesive layer and the auxiliary sealing layer are cured by irradiation of light of a same wavelength.

11. A display device comprising:

a window comprising a display area and a non-display area in a plan view;

a light-shielding pattern over the non-display area of the window and comprising a first area and a second area arranged further inward than the first area, the light-shielding pattern including a lower surface facing the window and an upper surface opposite to the lower surface;

a resin layer over the window, at least a portion of the resin layer being over the upper surface of the light-shielding pattern of the second area, the at least a portion of the resin layer directly contacting a portion of the upper surface of the light-shielding pattern of the second area; and

a display panel over the resin layer,

wherein an edge of the display panel over at least one side protrudes further outward than a corresponding edge of the resin layer, and

wherein the portion of the upper surface of the light-shielding pattern of the second area which directly contacts the at least a portion of the resin layer has a higher surface free energy than the upper surface of the light-shielding pattern of the first area, and a distance in a thickness direction from the window to the portion of the upper surface of the light-shielding pattern of the second area is less than or equal to a distance in the thickness direction from the window to the upper surface of the light-shielding pattern of the first area.

12. The display device of claim 11 , wherein the portion of the upper surface of the light-shielding pattern of the second area has a surface tension of 34 dyne/cm or more.

13. The display device of claim 11 , wherein the resin layer comprises a resin cured by irradiation of light.

14. The display device of claim 11 , further comprising an auxiliary sealing layer covering a side surface of the display panel and a corresponding side surface of the resin layer.
