Display device comprising a window and a polarization layer protruding more outward than a display panel and method for manufacturing the same

1 . A display device comprising:

a display panel having a display area and a non-display area, and comprising:

a first flat area comprising the display area; and

a bending area extending from the first flat area and comprising a portion of the non-display area;

a polarization layer on a first surface of the display panel and covering the display area and a portion of the non-display area adjacent to the display area; and

a window directly on the polarization layer and covering the display area and the portion of the non-display area adjacent to the display area, the window comprising a curved portion on the portion of the non-display area,

wherein the polarization layer and the window extend in a direction opposite to the bending area on a plane crossing a thickness direction of the display panel to protrude more outward than the display panel in the direction opposite to the bending area.

2 . The display device of claim 1 , wherein the polarization layer covers the first flat area and a portion of the bending area, is attached on the first flat area, and is separated from the bending area.

3 . The display device of claim 1 , wherein the display panel further has a second flat area extending from the bending area and comprising another portion of the non-display area.

4 . The display device of claim 3 , wherein the display panel is bent in the bending area so that a second surface of the first flat area faces a second surface of the second flat area.

5 . The display device of claim 3 , further comprising at least one of:

a cover panel on a second surface of the display panel in the first flat area and the second flat area;

a driving circuit on the first surface of the display panel in the second flat area; and

a circuit board connected to the display panel in the second flat area.

6 . The display device of claim 1 , wherein a thickness of the curved portion continuously and gradually decreases toward an edge of the window.

7 . The display device of claim 1 , wherein the window comprises a resin coating layer in direct contact with the polarization layer.

8 . The display device of claim 1 , further comprising a light blocking pattern on an edge of the polarization layer and covering a peripheral portion of the display area.

9 . A display device comprising:

a display panel having a flat area comprising a display area and a bending area comprising a portion of a non-display area;

a polarization layer attached on the flat area of the display panel and covering the flat area and a portion of the bending area adjacent to the flat area; and

a window directly on the polarization layer and covering the flat area and the portion of the bending area, the window comprising a curved surface on the portion of the bending area,

wherein the polarization layer and the window extend in a direction opposite to the bending area on a plane crossing a thickness direction of the display panel to protrude more outward than the display panel in the direction opposite to the bending area.

10 . The display device of claim 9 , wherein the polarization layer and the window comprise an edge protruding from both sides of the flat area on a plane crossing the thickness direction of the display panel and separated from the display panel, and

wherein the window comprises a curved portion at the edge.

11 . The display device of claim 9 , wherein the window has a curved portion in which a thickness of the curved portion continuously and gradually decreases toward an edge of the window.

12 . The display device of claim 9 , wherein the window comprises a resin coating layer in direct contact with the polarization layer.

13 . The display device of claim 9 , further comprising a light blocking pattern on an edge of the polarization layer and covering a peripheral portion of the display area.

14 . A method for manufacturing a display device, the method comprising:

manufacturing a mold comprising a bottom surface and a sidewall, and defining a groove having a curved surface at least in a portion of the sidewall;

preparing a display module comprising a display panel, and a polarization layer provided on a surface of the display panel;

forming a window comprising a curved portion corresponding to the curved surface of the groove by forming or placing a coating layer and at least a portion of the display module contacting the coating layer and curing the coating layer; and

separating the display module comprising the window from the mold,

wherein the polarization layer and the window extend in a direction opposite to a bending area of the display panel on a plane crossing a thickness direction of the display panel to protrude more outward than the display panel in the direction opposite to the bending area.

15 . The method of claim 14 ,

wherein the display module is placed on the groove so that the polarization layer contacts the coating layer.

16 . The method of claim 15 , wherein the manufacturing the mold comprises:

preparing a substrate of a size and a shape corresponding to the sizes and shapes of the polarization layer and the window;

forming the mold defining the groove of a size and a shape corresponding to the size and the shape of the substrate by applying a mold material onto a surface of the substrate and by curing; and

separating the substrate from the mold.

17 . The method of claim 14 , wherein the forming the window comprises:

forming the coating layer by applying a coating material onto the groove;

placing the display module on the groove so that a surface of the display module is in contact with the coating layer;

bonding the display module and the coating layer; and

forming the window by curing the coating layer.

18 . The display device of claim 14 , wherein the forming the window comprises:

placing the display module inside the groove;

forming the coating layer by applying a coating material on the display module; and

forming the window by curing the coating layer.
