A mask assembly includes a frame including a frame opening, and a mask disposed on the frame. The mask includes a body portion including an upper surface and a lower surface opposing each other and deposition openings spaced apart from each other, protrusions protruding from the upper surface and surrounding the corresponding deposition openings, and at least one step formation pattern overlapping the protrusions in a plan view and disposed in the body portion.

Mask assembly and method for manufacturing the same

A display device includes: a first main pixel being configured to emit light of a first color, and a second main pixel being configured to emit light of a second color; and a first auxiliary pixel and a second auxiliary pixel on the second area, the first auxiliary pixel being configured to emit light of the first color, and the second auxiliary pixel being configured to emit light of the second color, wherein a first virtual line passing through a center of an emission area of the first main pixel and a center of an emission area of the first auxiliary pixel is parallel to a first direction, and a second virtual line passing through a center of an emission area of the second main pixel and a center of an emission area of the second auxiliary pixel crosses the first direction.

Display device and electronic apparatus

A deposition mask for manufacturing a display panel includes a metallic base having a thickness of about 50 micrometers to about 200 micrometers and a plurality of openings defined therein, wherein at least some of the openings include a first opening having a first width and a second opening having a second width smaller than the first width respectively defined along a thickness direction of the metallic base, and wherein the metallic base includes a first part in which the first opening is defined, and a second part in which the second opening is defined, the second part having a width that increases in a direction downward from a top surface of the metallic base along the thickness direction of the metallic base.
