Abstract

According to one embodiment, a method of manufacturing a display device, includes preparing a first substrate configured such that a first display element module is formed on a first glass substrate, preparing a second substrate configured such that a first peeling auxiliary layer is formed on a second glass substrate, and then a first color filter layer is formed on the first peeling auxiliary layer, attaching the first display element module and the first color filter layer, and peeling the second glass substrate from the first peeling auxiliary layer.

Claims (12)

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

preparing a first substrate configured such that a first display element module comprising a plurality of display elements is formed in a first region on a first glass substrate and a second display element module comprising a plurality of display elements is formed in a second region on the first glass substrate, the second region being spaced apart from the first region;

preparing a second substrate configured such that a first peeling auxiliary layer having an island shape is formed on a second glass substrate, a second peeling auxiliary layer having an island shape, which is spaced apart from the first peeling auxiliary layer, is formed on the second glass substrate, and then a first color filter layer is formed on the first peeling auxiliary layer and a second color filter layer is formed on the second peeling auxiliary layer;

attaching the first display element module and the first color filter layer, and attaching the second display element module and the second color filter layer;

peeling the second glass substrate from the first peeling auxiliary layer and the second peeling auxiliary layer by radiating a laser beam toward the second substrate; and

cutting the first substrate between the first region and the second region.

2. The method of claim 1 , wherein said preparing the first substrate includes forming a third peeling auxiliary layer over the first region and the second region on the first glass substrate, and then forming the first display element module and the second display element module on the third peeling auxiliary layer.

3. The method of claim 2 , further comprising, after said cutting the first substrate, peeling the first glass substrate from the third peeling auxiliary layer by radiating a laser beam toward the first substrate of the first region, and peeling the first glass substrate from the third peeling auxiliary layer by radiating a laser beam toward the first substrate of the second region.

4. The method of claim 2 , wherein the first display element module and the second display element module include an inner surface barrier film between the third peeling auxiliary layer and the display elements.

5. The method of claim 1 , wherein the first peeling auxiliary layer and the second peeling auxiliary layer are transparent.

6. The method of claim 1 , wherein the first peeling auxiliary layer and the second peeling auxiliary layer are formed of a material consisting mainly of polyimide.

7. The method of claim 1 , wherein the first peeling auxiliary layer and the second peeling auxiliary layer have tapered end faces.
