Abstract

Provided is a display device including a display panel having a display region and a non-display region, a window covering the display panel, and an adhesive member interposed between the display panel and the window to adhere the window to the display panel. The composition material of the adhesive member includes an adhesive layer which is cured by light and a wavelength conversion material which converts the light into infrared rays.

First claim

What is claimed is:

1. A method for manufacturing a display device comprising:
providing an adhesive member between a display panel and a window, the adhesive member comprising an adhesive layer and a wavelength conversion material dispersed inside the adhesive layer;
disposing a light blocking layer on an entirety of a side surface and a portion of a back surface of the window;
irradiating the adhesive member with light configured to cure the adhesive layer, the wavelength conversion material converts the light into infrared rays;
measuring an intensity and an irradiation amount of the infrared rays emitted from the adhesive member corresponding to the light; and
adjusting an intensity or an irradiation amount of the light irradiated to the adhesive member on the basis of the measured intensity and the emission amount of the infrared rays,
wherein the light blocking layer has an integrated shape which is extending from the back surface of the window to the side surface of the window.

2. The method of claim 1 , wherein the light comprises ultraviolet rays, and the wavelength conversion material comprises a plurality of quantum dots which converts the ultraviolet rays into the infrared rays.

3. The method of claim 1 , wherein, when the light is irradiated to the adhesive member, the light is guided to a side of the adhesive member by a light guide unit.

4. The method of claim 1 , wherein adjusting the intensity or the irradiation amount of the light irradiated to the adhesive member is accomplished by increasing the intensity or the light amount of the light irradiated to the adhesive member when the measured intensity or the emission amount of the infrared rays is less than a preset value or decreasing the intensity or the light amount of the light irradiated to the adhesive member when the measured intensity or the emission amount of the infrared rays is greater than the preset value.
