Abstract

Claims (19)

1. A method of manufacturing a display device, the method comprising the steps of:

coupling a display panel to a first portion of a window member; and

coupling a protective film to a first portion of the display panel, the step of coupling of the protective film further comprising the steps of:

bending first portions, second portions, and third portions of the protective film to an angle of 90 degrees or more; and

disposing the bent protective film on the lower portion of the display panel,

wherein the first portions extend along an edge of the protective film in a second direction, the second portions extend along an edge of the protective film in a first direction that is normal to the second direction, and the third portions are disposed between the first portions and the second portions,

wherein a height, after bending, of the first portions and the second portions in a third direction normal to the first direction and the second direction is greater than a height of the third portions in the third direction.

2. The method of claim 1 , wherein the step of bending of the first portions, second portions, and third portions of the protective film further comprises the steps of:

placing the protective film on a support;

pressing an upper portion of the protective film to bend the first portions, second portions, and third portions at a first angle; and

pressing a side portion bent at the first angle to bend the first portions, second portions, and third portions at a second angle greater than the first angle.

3. The method of claim 2 , wherein an elastic member is disposed under the support, and wherein the step of pressing of the upper portion of the protective film comprises compressing the elastic member.

4. The method of claim 2 , wherein the step of pressing of the upper portion of the protective film further comprises the step of indirectly applying heat to the upper portion of the protective film.

5. The method of claim 2 , wherein the step of pressing of the side portion of the protective film further comprises the step of indirectly applying heat to a side portion of the protective film.

6. The method of claim 2 , wherein the step of pressing of the side portion of the protective film is performed by horizontally moving one or more side pressing members or by rotating the one or more side pressing members.

7. The method of claim 2 , wherein the step of bending of the first portions, second portions, and third portions of the protective film further comprises the steps of:

disposing a release film under the protective film before the placing the protective film on the support; and

removing the release film before coupling the display panel to the protective film.

8. The method of claim 2 , further comprising, before the step of coupling of the lower portion of the display panel to the protective film, bending outer portions of the window member and the display panel at a third angle smaller than the second angle at which the protective film is bent.
