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.

Claims8

Dependent claims

A display device, comprising:

a first resin layer including a display region, a terminal portion electrically connected with the display region, and a light blocking layer located between the display region and the terminal portion in a plan view, the display region 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
a second resin layer bonded to the first resin layer so as to face the first resin layer, wherein
the terminal portion includes external terminals,
the first resin layer includes wirings, each of which is connected to each of the external terminals and the display region,
the light blocking layer overlaps the wirings in a plan view, and
an insulation layer is arranged between the light blocking layer and the external terminals so that the light blocking layer is electrically isolated from the external terminals.
