Deposition mask and mask assembly having the same

摘要

A deposition mask and mask assembly having the same capable of improving deposition efficiency is discussed. Both ends of the deposition mask have a pointed cross section such that at least a part of the neighboring deposition masks overlap each other at a boundary therebetween when deposition masks are consecutively arranged in parallel.

主权项

1. A deposition mask, both ends of the deposition mask having a cross section such that at least a part of the deposition mask and a neighboring deposition mask overlap each other at a boundary therebetween when the deposition mask is consecutively arranged in parallel with the neighboring deposition mask,
wherein the cross section of one end of the deposition mask has first and second sectors which are asymmetric and meet each other at a first contact point, a cross section of one end of the neighboring deposition mask has third and fourth sectors which are asymmetric and meet each other at a second contact point, and each of the first and second contact points is asymmetric, pointed and protruded horn-shaped or arrow-shaped, and wherein the first contact point does not face the second contact point.
