Abstract

A method of manufacturing a display device includes forming a first resin layer on a first substrate; forming a plurality of regions on the first resin layer, the plurality of regions each including a display portion, a terminal portion and a light blocking layer located between the display portion and the terminal portion; forming a second resin layer on a second substrate; bonding the first substrate and the second substrate; directing first laser light along a first line and a second line enclosing the plurality of regions such that the first laser light is transmitted through the second substrate to irradiate the first resin layer and the second resin layer; and directing second laser light along a third line parallel to the light blocking layer such that the second laser light is transmitted through the second substrate to irradiate the light blocking layer and the second resin layer.

Claims (7)

1. A display device, comprising:

a first resin layer including a display portion, a terminal portion electrically connected with the display portion, and a light blocking layer located between the display portion and the terminal portion in a plan view, the display portion including a light emitting element including a positive electrode, a light emitting layer and a negative electrode, and the light blocking layer forming the same layer as the positive electrode and electrically isolated from the display portion and the terminal portion; and

a second resin layer bonded to the first resin layer so as to face the first resin layer.

2. The display device according to claim 1 , wherein the positive electrode and the light blocking layer have the same layer structure as each other.

3. The display device according to claim 1 , wherein the positive electrode and the light blocking layer are formed of a stacked film including a metal layer and a transparent conductive layer.

4. The display device according to claim 1 , wherein the positive electrode and the light blocking layer are provided on an insulating layer, and the insulating layer is not provided on the terminal portion.

5. The display device according to claim 1 , wherein the light emitting element is covered with a protective layer, and the protective layer is not provided on the light blocking layer or the terminal portion.
