Abstract

A display device includes a display panel having a display area, in which an image is displayed, and a non-display area, in which no image is displayed. A window overlaps the display panel. An antenna sheet is disposed between the display panel and the window. The antenna sheet includes a first antenna portion having a mesh shape, and a second antenna portion integrally connected to the first antenna portion and having a frame shape. The first antenna portion corresponds to the display area and the second antenna portion corresponds to the non-display area.

First claim

What is claimed is:

1. A display device comprising:
a display panel including a display area, in which an image is displayed, and a non-display area, in which no image is displayed;
a window overlapping the display panel; and
an antenna sheet disposed between the display panel and the window,
wherein the antenna sheet includes a first antenna portion having a mesh shape, and a second antenna portion integrally connected to the first antenna portion and having a solid-frame, non-mesh shape,
wherein the first antenna portion overlaps the display area,
wherein the second antenna portion overlaps the non-display area, and
wherein the antenna sheet includes a base material film and a metal layer that is disposed on the base material film, and the metal layer includes the first antenna portion and the second antenna portion.

2. The display device of claim 1 , wherein: the antenna sheet includes a resin layer disposed between the base material film and the metal layer, the resin layer includes a recess portion of a same planar shape as the metal layer, and the metal layer is disposed at the recess portion.

3. The display device of claim 1 , wherein the first antenna portion includes a plurality of first metal lines extending along a first direction and a plurality of second metal lines extending along a second direction crossing the first direction.

4. The display device of claim 3 , wherein: the antenna sheet includes a pair of long sides extended in a third direction and a pair of short sides extended in a fourth direction, and the first direction and the second direction each cross the third direction and the fourth direction.

5. The display device of claim 3 , wherein: the plurality of first metal lines and the plurality of second metal lines are integrally connected at side surfaces to each other, and end parts the plurality of first metal lines and end parts of the plurality of second metal lines are integrally connected to an inner side surface of the second antenna portion.

6. The display device of claim 3 , wherein: the first antenna portion includes a plurality of openings formed by the plurality of first metal lines and the plurality of second metal lines, and the plurality of openings have the same size and are uniformly disposed in the entire first antenna portion.

7. The display device of claim 1 , further comprising:
a polarization film disposed between the display panel and the antenna sheet; and
a first adhesive layer disposed between the antenna sheet and the polarization film.

8. The display device of claim 7 , further comprising:
a touch panel disposed between the antenna sheet and the window; and
a second adhesive layer disposed between the antenna sheet and the touch panel.

9. The display device of claim 7 , wherein: the window includes a transparent substrate and a light blocking film in contact with one surface of the transparent substrate, and the light blocking film corresponding to the non-display area, and the display device further includes a third adhesive layer disposed between the touch panel and the window.

10. The display device of claim 1 , wherein: the window includes a transparent substrate, the antenna sheet is in contact with one surface of the window, and the window includes a light blocking region corresponding to the second antenna portion of the antenna sheet.

11. The display device of claim 10 , further comprising: a polarization film and a touch panel disposed between the display panel and the antenna sheet, and the touch panel is disposed to be closer to the window than the polarization film.

12. The display device of claim 11 , further comprising: a fourth adhesive layer disposed between the polarization film and the touch panel; and a fifth adhesive layer disposed between the touch panel and the antenna sheet.

13. The display device of claim 12 , wherein the antenna sheet is disposed such that the base material film is in contact with one surface of the window and the metal layer is in contact with the fifth adhesive layer.

14. The display device of claim 1 , further comprising: a touch panel and a polarization film disposed between the antenna sheet and the window, and the polarization film is closer to the window than the polarization film is to the touch panel.

15. The display device of claim 14 , further comprising:
a sixth adhesive layer disposed between the display panel and the antenna sheet; and
a seventh adhesive layer disposed between the antenna sheet and the touch panel.

16. The display device of claim 14 , wherein: the window includes a transparent substrate and a light blocking film in contact with one surface of the transparent substrate, the light blocking film corresponding to the non-display area, and the display device further includes an eighth adhesive layer disposed between the polarization film and the window.

17. The display device of claim 1 , wherein the display panel includes the color filter layer or the touch sensing unit.

18. The display device of claim 1 , wherein: the display panel is a flexible display panel that is at least partially bent, and the antenna sheet and the window are bent corresponding to a curvature of the flexible display panel.

19. A mobile electronic device, comprising:
a display panel having a display area in which a plurality of pixels are disposed, and a peripheral region surrounding the display area;
a window having a light-blocking frame and a transparent interior, the light-blocking frame substantially aligning with the peripheral region of the display panel and the transparent interior substantially aligning with the display area of the display panel; and
an antenna sheet disposed between the display panel and the window,
wherein the antenna sheet includes a solid portion substantially aligning with the light-blocking frame of the window and the peripheral region of the display panel,
wherein the antenna sheet further includes a mesh portion substantially aligning with the transparent interior of the window and the display area of the display panel, the solid portion and the mesh portion of the antenna sheet being disposed within a single layer, and
wherein the antenna sheet further includes a base material film and a metal layer that is disposed on the base material film, and the metal layer includes the solid portion and the mesh portion.
