Abstract

A display device includes a display pane, a frame, a first protruding structure, and an adhesive structure. The display panel has a display surface. The frame surrounds the display panel and has an opening. The first protruding structure is connected to and protrudes from the frame, in which the first protruding structure and the display surface are located at the same side of the frame and the display panel. The adhesive structure adheres to the display surface of the display panel, a top surface of the first protruding structure opposite to the frame, and the frame.

First claim

1 . A display device, comprising:
a display panel having a display surface; a frame surrounding the display panel and having an opening; a first strip protrusion protruding from the frame and substantially extending along a first direction that intersects an inner edge of the opening at a first angle; a second strip protrusion protruding from the frame and substantially extending along a second direction that intersects the inner edge of the opening at a second angle, wherein the second angle is substantially the same as the first angle and the second direction is different from the first direction; and an adhesive structure adhering to the display surface of the display panel and top surfaces of the first and second strip protrusions opposite to the frame.

2 . The display device of claim 1 , wherein the first strip protrusion has a side surface does not contact the adhesive structure.

3 . The display device of claim 1 , wherein a portion of the frame between the first and second strip protrusions does not contact the adhesive structure.

4 . The display device of claim 1 , wherein a first coefficient of thermal expansion of the display panel is smaller than a second coefficient of thermal expansion of the frame.

5 - 8 . (canceled)

9 . The display device of claim 1 , wherein a first height of the first strip protrusion relative to the frame is substantially equal to or smaller than a second height of the display panel relative to the frame.

10 . The display device of claim 1 , wherein a thickness of the adhesive structure is smaller than a height of the first strip protrusion relative to the frame.

11 . The display device of claim 1 , wherein the adhesive structure comprises an adhesive layer, a first molding layer, an electromagnetic shielding layer, and an insulating layer which are sequentially stacked on each other, and the adhesive layer of the adhesive structure adheres to the display surface of the display panel and the top surfaces of the first and second strip protrusions.

12 . The display device of claim 11 , wherein the first molding layer is a fiber structure.

13 . The display device of claim 11 , wherein the adhesive structure further comprises a second molding layer between the electromagnetic shielding layer, and the insulating layer.
