Claim 8:
9. A display device comprising a display panel, wherein the display panel comprises:
a display substrate comprising a display region, within which an opening region and an isolation region surrounding the opening region are arranged;
a light-emitting layer formed on the display region;
a blocking layer formed on a surface of the light-emitting layer away from the display substrate; and
a first packaging layer covering the light-emitting layer and the blocking layer,
wherein the first packaging layer is patterned through a photoresist layer covering a side of the first packaging layer away from the display substrate to form a first through hole on the first packaging layer;
a second through hole is respectively formed at a part of the blocking layer corresponding to the first through hole and a part of the light-emitting layer corresponding to the first through hole;
wherein the light-emitting layer covers an overall area of the display region,
wherein an overall area of the opening region and at least a part of the isolation region are surrounded by an outline of an orthographic projection of the blocking layer on the display substrate, and
wherein an orthographic projection of the first through hole on the display substrate is surrounded by an outline of the orthographic projection of the blocking layer on the display substrate, and an orthographic projection of the first through hole on the display substrate covers the overall area of the opening region and at least a part of the isolation region.
