Metal mask structure

Abstract

The present invention provides a metal mask structure, including: an outer frame, a protrusion region, and a first connection region. The outer frame surrounds and defines a central hollowed-out region and includes at least a first side frame. The protrusion region protrudes from the first side frame toward the central hollowed-out region, and is provided with at least one hole. The protrusion region is connected to the first side frame at a connection side edge. The first connection region connects the protrusion region to the first side frame at one end of the connection side edge, and includes a first side edge, a second side edge, and a third side edge. The first side edge continues from the connection side edge, the second side edge extends transversely from a junction of the first side edge and the connection side edge toward the central hollowed-out region, and two ends of the third side edge are respectively connected to endpoints of the first side edge and the second side edge away from the connection side edge.
