Display device
A display device including a display panel which includes a main region configured to display an image and a protrusion region protruding from one side of the main region to be bent, a lower film which is disposed on a rear surface of the display panel, and a metal layer which is disposed on a rear surface of the lower film and comprises a notch region. The protrusion region includes a first bending portion which has a first curvature and a pad portion which faces the main region in a thickness direction of the display panel, and the pad region is disposed in the notch region.
1. A display device comprising:
a display panel which comprises a main region configured to display an image and a protrusion region protruding from one side of the main region configured to be bent;
a lower film comprising a heat dissipation layer, which is disposed on a rear surface of the display panel; and
a metal layer which is disposed on a rear surface of the lower film and comprises a first edge portion, a second edge portion, and a notch region between the first edge portion and the second edge portion at one end thereof, the first edge portion and the second edge portion extending in a same direction in a plan view of the metal layer,
wherein the notch region has a shape which is recessed inwardly into the display panel from the first and second edge portions of the metal layer so as to accommodate at least a portion of the protrusion region of the display panel,
the protrusion region comprises a first bending portion which has a first curvature and a pad portion which faces the main region in a thickness direction of the display panel, and
the pad portion is disposed in the notch region.
2. The display device of claim 1 , wherein the notch region is an incision region defined in the metal layer.
3. The display device of claim 1 , wherein a shape of the notch region is the same as a shape of the pad portion.
4. The display device of claim 3 , wherein the notch region surrounds an edge of the pad portion when viewed from above.
5. The display device of claim 1 , wherein a size of the notch region is greater than a size of the pad portion.
6. The display device of claim 1 , wherein the lower film is disposed on the main region and the pad portion.
7. The display device of claim 6 , wherein the lower film comprises an interval maintenance member between the pad portion and the main region, the interval maintenance member overlaps the pad portion.
8. The display device of claim 1 , further comprising a touch panel disposed on the display panel.
9. The display device of claim 8 , wherein the touch panel comprises a touch circuit board, and
the touch circuit board comprises a second bending portion which has a second curvature and a non-bending portion which is configured to face the main region in the thickness direction of the display panel.
10. The display device of claim 9 , wherein the non-bending portion is configured to be disposed in the notch region.
11. The display device of claim 9 , wherein the first curvature is less than the second curvature.
12. The display device of claim 9 , wherein the first bending portion and the second bending portion are spaced apart from each other.
13. The display device of claim 1 , further comprising a stress control member disposed on the protrusion region,
wherein a portion of the stress control member overlaps the notch region.
14. The display device of claim 1 , further comprising a lower cover disposed under the metal layer.
15. The display device of claim 14 , wherein an inner side surface of the lower cover, which faces the first bending portion, has a third curvature.
16. The display device of claim 15 , wherein the first curvature is less than the third curvature.
17. The display device of claim 15 , wherein the inner side surface of the lower cover and the first bending portion are spaced apart from each other.
18. A display device comprising:
a display panel which comprises a main region configured to display an image and a protrusion region protruding from one side of the main region configured to be bent;
a lower film which is disposed on a rear surface of the display panel; and
a metal layer disposed on a rear surface of the lower film, the metal layer comprising a first edge portion, a second edge portion, and a notch region between the first edge portion and the second edge portion at one end thereof, the first edge portion and the second edge portion extending in a same direction in a plan view of the metal layer,
wherein:
the metal layer is configured to surround the protrusion region of the display panel when the display panel is bent, and the metal layer does not overlap the protrusion region in a thickness direction thereof; and
the notch region has a shape which is recessed inwardly into the display panel from the first and second edge portions of the metal layer so as to accommodate at least a portion of the protrusion region of the display panel.
