Display device and display device manufacturing method
A display device includes a display panel including a main display surface and a first sub-display surface that protrudes from one side of the main display surface, an adhesive layer disposed below the display panel, and a thermoforming film disposed below the adhesive layer, and the first sub-display surface may include a first top surface and a first side surface that defines a predetermined angle with the first top surface.
1. A display device comprising:
a display panel comprising a main display surface and a first sub-display surface which protrudes from one side of the main display surface;
an adhesive layer disposed below the display panel; and
a thermoforming film disposed below the adhesive layer,
wherein the first sub-display surface comprises a first top surface and a first side surface which defines a predetermined angle with the first top surface, and
the main display surface has a width greater than a width of the first sub-display surface in a predetermined direction perpendicular to an arrangement direction along which the main display surface and the first sub-display surface are arranged in a plan view.
2. The display device of claim 1 , wherein the main display surface and the first top surface display an image in a first direction, and the first side surface displays an image in a second direction crossing the first direction.
3. The display device of claim 1 , wherein the display panel further comprises a second sub-display surface, a third sub-display surface, and a fourth sub-display surface,
the first sub-display surface and the second sub-display surface are spaced apart from each other with the main display surface therebetween in a first direction, and
the third sub-display surface and the fourth sub-display surface are spaced apart from each other with the main display surface therebetween in a second direction crossing the first direction.
4. The display device of claim 3 , wherein the second sub-display surface comprises a second top surface and a second side surface which defines a predetermined angle with the second top surface,
the third sub-display surface comprises a third top surface and a third side surface which defines a predetermined angle with the third top surface, and
the fourth sub-display surface comprises a fourth top surface and a fourth side surface which defines a predetermined angle with the fourth top surface,
wherein the first side surface faces the second side surface, and the third side surface faces the fourth side surface.
5. The display device of claim 1 , wherein the thermoforming film comprises an amorphous polyester film.
6. The display device of claim 1 , wherein the thermoforming film has a shape corresponding to a shape of the display panel.
7. The display device of claim 1 , wherein the thermoforming film has a surface area greater than a surface area of the display panel in the plan view.
8. The display device of claim 1 , wherein the thermoforming film comprises a first area which is overlapped with the display panel and a second area which is not overlapped with the display panel.
9. The display device of claim 8 , wherein at least one hole is defined in the second area.
10. The display device of claim 1 , further comprising a window disposed on the display panel and covering the display panel.
11. The display device of claim 10 , wherein the window comprises a top window which covers the main display surface and the first top surface and a side window which covers the first side surface.
