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 device includes: a first electrode; a hole transport region disposed on the first electrode; a first emission layer disposed on the hole transport region, and which emits light of a first wavelength; a second emission layer disposed on the hole transport region, and which emits light of a second wavelength different from the first wavelength; an electron transport region disposed on the first emission layer and the second emission layer; a second electrode disposed on the electron transport region; and a capping layer disposed on the second electrode. In exit light emitted to an upper surface of the capping layer, the exit light has a maximum intensity at an azimuth angle of about 25° to about 35°.

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.
