    Abstract: A deposition mask includes a first area defining a clamping portion at ends of the deposition mask and to which a force is applied to extend the deposition mask in a length direction thereof, a recess area adjacent to the first area and defining a recess at the ends; and a pattern portion including a plurality of pattern holes through which a deposition material passes. Along the length direction, a plurality of first pattern portions are arranged in the first area and a plurality of second pattern portions arranged in the recess area. The force applied extends the first area and does not extend the recess area. The force not applied defines non-extended positions of the pattern portions, and for the non-extended positions of the first and second pattern portions, a first distance between adjacent first pattern portions is less than a second distance between adjacent second pattern portions.

    Abstract: A light emitting devices includes a first electrode, a hole transport region on the first electrode, a first emission layer on the hole transport region, the first emission layer to emit light of a first wavelength, a second emission layer on the hole transport region and to emit light of a second wavelength, an electron transport region on the first and second emission layers, and a second electrode on the electron transport region. The first emission layer includes a first sub-emission layer including a first hole transport host and a first sub-dopant to emit the light of the first wavelength, and a second sub-emission layer including a first electron transport and a second sub-dopant to emit the light of the first wavelength. The second emission layer includes a second hole transport host, a second electron transport host, and a second dopant to emit the light of the second wavelength.

    Abstract: A deposition mask includes a first area defining a clamping portion at ends of the deposition mask and to which a force is applied to extend the deposition mask in a length direction thereof, a recess area adjacent to the first area and defining a recess at the ends; and a pattern portion including a plurality of pattern holes through which a deposition material passes. Along the length direction, a plurality of first pattern portions are arranged in the first area and a plurality of second pattern portions arranged in the recess area. When the force is applied to the clamping portion, the deposition mask is extended in the length direction thereof and defines non-extended positions of the pattern portions, and for the non-extended positions of the first and second pattern portions, a first distance between adjacent first pattern portions is less than a second distance between adjacent second pattern portions.

    Abstract: A mask assembly and an apparatus and method for manufacturing a display apparatus are provided. A mask assembly includes a mask frame and a mask on the mask frame and having at least one opening. The mask includes a mask body portion having the at least one opening, and a protruding portion arranged to surround the at least one opening and including an inner surface defining the at least one opening, the protruding portion protruding from the mask body portion and configured to protrude toward a display substrate and contact the display substrate. A deposition material is configured to pass through the at least one opening to be deposited in an entire display area of a display panel including a plurality of pixels.
