Abstract: A display device includes a first pixel, a second pixel, and a third pixel each of which includes a first electrode on a substrate, a first sub-light emitting portion on the first electrode, a first charge generation layer on the first sub-light emitting portion, a second sub-light emitting portion on the first charge generation layer, and a second electrode on the second sub-light emitting portion. The second sub-light emitting portion includes a hole transport layer on the first charge generation layer and an emission layer on the hole transport layer. The hole transport layer of the first pixel is on the first charge generation layer of the first pixel and completely covers the first charge generation layer of the first pixel. A part of an edge of the hole transport layer of the first pixel overlaps the first charge generation layer of the second pixel.

Abstract: A magnet assembly includes a yoke plate disposed on a plane, and a magnetic field generator which is disposed on the yoke plate and includes magnet parts including magnet units, magnetic bodies, and non-magnetic bodies. The magnetic bodies overlap the magnet parts in a plan view. The non-magnetic bodies overlap an area between the magnet units in a plan view. The magnet assembly operates in one of a first mode and a second mode. The magnetic field generator generates a magnetic field below the magnetic bodies and the non-magnetic bodies in the first mode and does not substantially generate the magnetic field below the magnetic bodies and the non-magnetic bodies in the second mode.
