Abstract

A display device, includes: a substrate including pixel areas and a transmissive area between the pixel areas; a pixel circuit layer including at least one transistor on each of the pixel areas; and a light-emitting element layer on the pixel circuit layer and including at least one light-emitting element at each of the pixel areas and coupled to the at least one transistor, and a transparent organic layer at the transmissive area, wherein the light-emitting element layer further includes: a first electrode at the pixel areas, a first inorganic layer at the first electrode, an organic layer covering the first inorganic layer and the transparent organic layer, and a second inorganic layer on the organic layer.

First claim

What is claimed is:

1. A method of manufacturing a display device, comprising:
preparing a panel including a plurality of insulating layers on a substrate, at least one transistor formed between the insulating layers in each of pixel areas of the substrate, and a groove formed by penetrating through at least one of the insulating layers in a transmissive area of the substrate, the transmissive area being located between the pixel areas;
forming a dummy pattern on the insulating layers along an edge of the transmissive area;
forming a transparent organic layer in the groove of the transmissive area;
forming a photoresist on the transparent organic layer;
removing the dummy pattern;
forming a light-emitting element on the substrate;
forming a first inorganic layer on an entirety of the substrate; and
removing the photoresist.

2. The method according to claim 1 , further comprising:
forming an organic layer that covers the transparent organic layer, exposed by removing the photoresist, and the first inorganic layer; and
forming a second inorganic layer on the organic layer.

3. The method according to claim 2 , wherein forming the light-emitting element comprises:
forming an emission layer in the pixel areas; and
forming a first electrode on an entirety of the substrate using a chemical vapor deposition technique,
wherein the first electrode is discontinuous between the transmissive area and the pixel areas by the photoresist.
