Abstract
A method for manufacturing the display device includes preparing a display panel on which a folding area folded with reference to a virtual folding axis and first and second non-folding areas, which are adjacent to both sides of the folding area, are defined and which displays an image, providing a resin on a first surface of the display panel, primarily hardening the resin, and secondarily hardening first and second resin areas of the resin, which respectively correspond to the first non-folding area and the second non-folding area of the display panel.
Claims14
A method for manufacturing a display device, the method comprising:
- preparing a display panel which defines a folding area folded with reference to a virtual folding axis, a first non-folding area and a second non-folding area adjacent to both sides of the folding area, and which displays an image;
- providing a resin on a first surface of the display panel;
- primarily hardening the resin;
- and
- secondarily hardening a first resin area of the resin, which corresponds to the first non-folding area of the display panel, and a second resin area of the resin, which corresponds to the second non-folding area of the display panel,
- wherein the primarily hardening the resin comprises a first light irradiation process,
- wherein the secondarily hardening the first resin area and the second resin area comprises a second light irradiation process and a third light irradiation process,
- wherein the second light irradiation process is performed on a top surface of the first resin area along a first movement path, and
- the third light irradiation process is performed on a top surface of the second resin area along a second movement path.
A method for manufacturing a display device, the method comprising:
- preparing a display panel which defines a folding area folded with reference to a virtual folding axis, a first non-folding area and a second non-folding area, which are adjacent to both sides of the folding area, and which displays an image;
- providing a first resin on a first resin area corresponding to the first non-folding area of a first surface of the display panel and providing a second resin on a second resin area corresponding to the second non-folding area of the first surface of the display panel;
- primarily hardening the first resin and the second resin;
- providing a third resin on a third resin area corresponding to the folding area of the first surface of the display panel;
- and
- secondarily hardening the third resin,
- wherein each of the first resin and the second resin comprises a material having a modulus different from a modulus of the third resin.
