    Abstract: A mask assembly includes a mask frame in which a first opening is defined, the mask frame including a front surface through which the first opening extends, and a deposition mask which is attached to the front surface of the mask frame and through which a plurality of second openings is defined. The mask frame includes an in which the front surface extends along a direction of gravity, the deposition mask includes an initial mask which is attached to the front surface of the mask frame in the thereof and through which the plurality of second openings is defined, and the of the mask frame having the front surface which extends along the direction of gravity disposes the first opening of the mask frame corresponding to all of the plurality of second openings of the initial mask along the direction of gravity.

    Abstract: A display device includes a first region including a first light emitting element including a first electrode, a second region including a second light emitting element including a second electrode, a pixel defining layer including a first sidewall defining a first opening corresponding to the first electrode and a second sidewall defining a second opening corresponding to the second electrode, a first spacer which protrudes from the pixel defining layer in the first region and includes a first edge closest to the first opening, and a second spacer which protrudes from the pixel defining layer in the second region and includes a second edge closest to the second opening. A distance between the first sidewall and the first edge, is smaller than a distance between the second sidewall and the second edge.

    Abstract: A mask chuck may include a base plate including a central region and an edge region surrounding the central region, a head part including a first surface connected to the edge region of the base plate and configured to move on the edge region to be close to the central region or away from the central region, and a pad part disposed on a second surface of the head part opposite to the first surface of the head part. The edge region may include a first edge region extending in a first direction, a second edge region extending in the first direction and spaced apart from the first edge region in a second direction crossing the first direction, a third edge region extending in the second direction, and a fourth edge region extending in the second direction and spaced apart from the third edge region in the first direction.
