Abstract

A display device includes a support member including a through-hole, a polymer film disposed above a support member, a display panel disposed above a polymer film, a protective layer disposed above a display panel, and an electronic module. The polymer film includes a protrusion portion protruding toward the support member. The electronic module is disposed in a position corresponding to the through-hole and facing the protrusion portion.

Claims (41)

1. A display device comprising:

a support member including a through-hole;

a polymer film disposed above the support member and including a protrusion portion protruding toward the support member, the protrusion portion including a polymer resin;

a display panel disposed above the polymer film;

a protective layer disposed above the display panel; and

an electronic module disposed in a position corresponding to the through-hole and facing the protrusion portion, wherein

the protrusion portion has a transmittance of about 85% or more in a wavelength range of about 400 nm to about 800 nm.

2. The display device of claim 1 , wherein the protrusion portion and the electronic module overlap each other within the through-hole.

3. The display device of claim 1 , wherein

a bottom surface of the protrusion portion contacts a top surface of the electronic module, and

a top surface of the protrusion portion directly contacts a bottom surface of the polymer film.

4. The display device of claim 1 , wherein an area of a bottom surface of the protrusion portion is greater than or equal to an area of a top surface of the electronic module.

5. The display device of claim 1 , wherein a bottom surface of the protrusion portion comprises an uneven pattern.

6. The display device of claim 1 , further comprising a transparent adhesive layer disposed between the protrusion portion and the electronic module.

7. The display device of claim 1 , further comprising a light blocking portion that surrounds a side surface of the protrusion portion.

8. The display device of claim 7 , wherein the light blocking portion fills at least a portion of the through-hole.

9. The display device of claim 1 , wherein

the protrusion portion comprises first polymer resin, and

the polymer film comprises second polymer resin different from the first polymer resin.

10. The display device of claim 1 , wherein an edge of the protrusion portion contacts a surface of the support member.

11. The display device of claim 1 , wherein the protrusion portion has a trapezoidal shape in a cross-sectional view, the trapezoidal shape having a short side and a long side facing each other.

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

providing a display panel;

forming a polymer film below the display panel, the polymer film including a protrusion portion that includes a polymer resin;

disposing a protective layer above the display panel;

disposing a support member below the polymer film, the support member including a through-hole;

bonding the support member, the polymer film, the display panel, and the protective layer with each other; and

disposing an electronic module in a position that corresponds to the through-hole and faces the protrusion portion, wherein

the protrusion portion protrudes toward the support member, and

the protrusion portion has a transmittance of about 85% or more in a wavelength range of about 400 nm to about 800 nm.

13. The method of claim 12 , wherein

the protrusion portion comprises first polymer resin, and

the polymer film comprises second polymer resin different from the first polymer resin.

14. The method of claim 12 , wherein the forming of the polymer film includes:

forming the protrusion portion and the polymer film by an inkjet process; and

photo-curing the protrusion portion and the polymer film.

15. The method of claim 12 , wherein the protrusion portion and the polymer film are formed simultaneously.

16. The method of claim 12 , wherein the forming of the polymer film comprises forming an uneven pattern on a bottom surface of the protrusion portion that faces the electronic module.

17. The method of claim 12 , wherein the bonding of the support member, the polymer film, the display panel, and the protective layer comprises forming an adhesive layer between the protrusion portion and the electronic module.

18. The method of claim 12 , wherein the bonding of the support member, the polymer film, the display panel, and the protective layer comprises disposing a light blocking portion between the protrusion portion and the through-hole.

19. The method of claim 12 , wherein the bonding of the support member, the polymer film, the display panel, and the protective layer comprises providing a roller above the protective layer to perform a pressing process on the protective layer.
