Abstract

Provided is a mask assembly, an apparatus, and a method of manufacturing a display apparatus using such mask assembly and apparatus. The mask assembly deposits a deposition material on a first pixel among a plurality of pixels disposed on a device substrate and including the first pixel and a second pixel includes a mask substrate, a molding layer stacked on the mask substrate and including a hole corresponding to a position of the second pixel, a blocking plate detachably mounted in the hole and configured to block the second pixel from the deposition material by covering the second pixel when the blocking plate is detached from the hole.

Claims (19)

1. An apparatus for manufacturing a display device, the apparatus comprising:

a mask assembly configured to deposit a deposition material on a first pixel disposed on a device substrate comprising the first pixel and a second pixel;

a first magnetic member configured to ascend above the device substrate; and

a second magnetic member configured to ascend below the mask assembly,

wherein the mask assembly comprises:

a mask substrate,

a molding layer stacked on the mask substrate, the molding layer comprising a hole corresponding to a position of the second pixel disposed on the device substrate, and

a blocking plate detachably mounted in the hole and configured to block the second pixel from the deposition material by covering the second pixel when the blocking plate is detached from the hole,

the first magnetic member is configured to pull the blocking plate from the hole to the second pixel, and

the second magnetic member is configured to pull the blocking plate from the second pixel to the hole.

2. The apparatus of claim 1 , wherein the mask substrate comprises a conductive material.

3. The apparatus of claim 1 , wherein the molding layer comprises at least one of acrylic resin, polyimide (PI), benzocyclobutene (BCB), a non-photosensitive organic material layer, and a non-photosensitive inorganic material layer.

4. The apparatus of claim 1 , wherein the hole extends to correspond to positions of a plurality of second pixels that are adjacent to each other and disposed on the device substrate, and

the blocking plate extends to cover the plurality of second pixels that are adjacent to each other when the blocking plate is detached from the hole.

5. The apparatus of claim 1 , wherein the blocking plate comprises a conductive material.

6. The apparatus of claim 1 , wherein the device substrate further comprises a first electrode, a pixel-defining layer partially exposing the first electrode, and a spacer protruding from the pixel-defining layer, and

the blocking plate comprises an accommodation hole that accommodates the spacer.

7. The apparatus of claim 1 , wherein the device substrate comprises a first alignment key, and

at least one of the mask substrate and the molding layer comprises a second alignment key corresponding to the first alignment key.
