Abstract

A display device and a method of manufacturing a display device are provided. A manufacturing method of a display apparatus includes forming a display module including a first area and including a display panel including lower and upper surfaces opposite each other, a first film under the lower surface of the display panel, a second film on the upper surface of the display panel, and an adhesive layer between the lower surface of the display panel and the first film; weakening an adhesive force of a first adhesive portion of the adhesive layer in the first area to be weaker than an adhesive force of a second adhesive portion of the adhesive layer outside the first area; cutting the first film and the adhesive layer; and removing a portion of the first film and the first adhesive portion from the first area.

Claims (10)

1. A display device comprising:

a display panel comprising a first area defined therein and comprising a lower surface and an upper surface opposite the lower surface;

a first film under the lower surface of the display panel and comprising a film groove defined therein to overlap with the first area;

a second film on the upper surface of the display panel; and

an adhesive layer between the lower surface of the display panel and the first film and comprising an adhesive groove defined therein to overlap with the first area, wherein the display panel comprises a base substrate defining the lower surface of the display panel, a first portion of the base substrate in the first area having a first thickness, and a second portion of the base substrate outside the first area having a second thickness greater than the first thickness.

2. The display device of claim 1 , wherein the base substrate comprises polyimide.

3. The display device of claim 1 , wherein a surface roughness of the first portion of the base substrate is greater than a surface roughness of the second portion of the base substrate.

4. The display device of claim 1 , wherein the first area crosses the display panel in a first direction when viewed in a plan view and is bent with respect to a reference axis defined in the first area and extending in the first direction.

5. The display device of claim 4 , wherein the display panel comprises a display area to display an image and a non-display area adjacent to the display area, and the first area is defined in the non-display area.

6. The display device of claim 4 , further comprising a printed circuit board connected to the non-display area of the display panel, wherein the first area is bent with respect to the reference axis between the display area and the printed circuit board.
