Display device and method for fabricating display device

1. A display device comprising:

a display panel;

a window on the display panel; and

an adhesive member between the display panel and the window,

wherein the window comprises a base substrate and a light-shielding pattern layer, the base substrate comprising a first region overlapping the display panel, and a second region extending and protruding outward from the display panel, the light-shielding pattern layer being on the first region and the second region and comprising a groove adjacent to an outer edge surface of the display panel, and

wherein the groove comprises an inner wall and an outer wall, the inner wall of the groove being aligned with the outer edge surface of the display panel.

2. The display device of claim 1 , wherein the groove extends linearly along the outer edge surface of the display panel.

3. The display device of claim 2 , wherein the display panel has a rectangular shape, and the groove extends along at least one side of the rectangular shape.

4. The display device of claim 1 , wherein a width of the groove is 1 μm to 100 μm, and a depth of the groove is 0.1 μm or more and is less than a thickness of the light-shielding pattern layer.

5. The display device of claim 1 , wherein a tip of the adhesive member overlaps at least part of the groove.

6. The display device of claim 1 , wherein the window has one surface facing the display panel, and another surface opposite to the one surface, the light-shielding pattern layer being on the one surface of the window.

7. The display device of claim 1 , wherein the display panel comprises a first substrate, and a second substrate facing the first substrate and spaced from the first substrate.

8. The display device of claim 1 , wherein the display panel comprises an organic light-emitting element.

9. The display device of claim 1 , wherein the adhesive member comprises an optically clear resin (OCR).

10. A method for fabricating a display device, the method comprising:

preparing a window comprising a base substrate, and a light-shielding pattern layer on a peripheral portion of the base substrate;

forming a groove on the light-shielding pattern layer; and

laminating a display panel and the window via an adhesive member to form a laminate,

wherein the base substrate of the laminate comprises a first region overlapping the display panel, and a second region extending and protruding outward from the display panel,

wherein the light-shielding pattern layer of the laminate is on the first region and the second region,

wherein the groove of the light-shielding pattern layer of the laminate is aligned with an outer edge surface of the display panel, and

wherein the groove comprises an inner wall and an outer wall, the inner wall of the groove being aligned with the outer edge surface of the display panel.

11. The method of claim 10 , wherein forming the groove comprises irradiating a laser on the basis of the outer edge surface of the display panel.

12. The method of claim 10 , wherein forming the groove comprises formation of a scratch, using a knife, on the basis of the outer edge surface of the display panel.

13. The method of claim 10 , wherein the groove is formed linearly along the outer edge surface of the display panel.

14. The method of claim 13 , wherein the display panel has a rectangular shape, and the groove extends along at least one side of the rectangular shape.

15. The method of claim 10 , wherein a width of the groove is 1 μm to 100 μm, and a depth of the groove is 0.1 μm or more and is less than a thickness of the light-shielding pattern layer.

16. The method of claim 10 , wherein the window has one surface facing the display panel, and an other surface opposite to the one surface, and

wherein the method further comprises acquiring data, by ultrasonic measurement on a vicinity of a frame of the laminate, from the other surface of the window after forming the laminate.

17. The method of claim 16 , wherein the acquiring the data via ultrasonic measurement comprises acquisition of data about a filling condition of the adhesive member and data about a position of the groove.

18. A method for fabricating a display device, the method comprising:

preparing a display panel and a window comprising a base substrate and a light-shielding pattern layer, the base substrate comprising a first region on the display panel and overlapping the display panel, a second region extending and protruding outward from the display panel, the light-shielding pattern layer being on the first region and the second region of the base substrate;

preparing a laminate comprising an adhesive member between the display panel and the window; and

forming a groove aligned with an outer edge surface of the display panel, in the light-shielding pattern layer.

19. The method of claim 18 , wherein the window has one surface facing the display panel, and an other surface opposite to the one surface, and

wherein the method further comprises acquiring data, by ultrasonic measurement on a vicinity of a frame of the laminate, from the other surface of the window after forming the laminate.
