    Abstract: A mask assembly includes a frame including first to fourth lateral parts connected to define a frame opening, an open sheet including a body part in which sheet openings arranged in a first direction and a second direction are defined to overlap the frame opening and a connecting part protruding from the body part and at least partially overlapping the frame, and masks, each including a deposition part having deposition openings defined therein and coupling parts that protrude from the deposition part and that are spaced apart from each other with the deposition part therebetween. The connecting part includes a first connecting part and a second connecting part that overlap the frame and a third connecting part and a fourth connecting part that at least partially overlap the frame.

    CPC classification number: C23C14/042

    Abstract: A mask assembly includes an open mask including first and second open openings defined therethrough and alternately arranged in a first direction, first unit masks respectively corresponding to the first open openings, and second unit masks respectively corresponding to the second open openings. Each of the first unit masks includes a first deposition portion through which first deposition openings are defined and first and second welding portions extending from the first deposition portion to the first direction and a direction opposite to the first direction, respectively. Each of the second unit masks includes a second deposition portion through which second deposition openings are defined and third and fourth welding portions extending from the second deposition portion to a second direction and a direction opposite to the second direction.

    Abstract: A display device includes a base layer, a circuit layer on the base layer, and a plurality of light emitting units on the circuit layer. Each of the light emitting units includes a lower electrode, a pixel definition layer on the lower electrode, the pixel definition layer having a pixel opening to expose the lower electrode, a functional layer on the lower electrode, the functional layer including a light emitting layer, an upper electrode on the functional layer, and an encapsulation layer on the upper electrode. At least one light emitting unit from among the plurality of light emitting units is at a different layer from other light emitting units from among the plurality of light emitting units in a thickness direction, and the pixel openings of the plurality of light emitting units do not overlap each other.
