Abstract: A display device includes a substrate that includes a display area and a peripheral area outside the display area, a display element on the display area, a peripheral circuit on the peripheral area, the peripheral circuit including a thin film transistor, a first shielding layer on the peripheral circuit. and a second shielding layer on the first shielding layer. At least one of the first shielding layer and the second shielding layer includes a hole. One shielding layer of the first shielding layer and the second shielding layer includes the hole and overlaps the other one of the first shielding layer and the second shielding layer.

Abstract: An apparatus for manufacturing a display device includes a mask assembly, and a deposition source including a deposition part that supplies deposition material to the mask assembly. The deposition part includes a deposition frame including an inner space, a crucible disposed in the inner space of the deposition frame to be withdrawn from the deposition frame and accommodating the deposition material, a nozzle connected to the crucible and that sprays the deposition material accommodated in the crucible, a first heating portion disposed in the inner space of the deposition frame and that heats the deposition material accommodated in the crucible, and a second heating portion being movable between a first position at which the nozzle is heated and a second position at which a withdrawal space so that the crucible is withdrawn from the deposition frame.

Abstract: A display device includes a substrate. The display unit is disposed on the substrate and includes a pixel circuit and a display element electrically connected to the pixel circuit. A driving circuit is disposed outside of the display unit. The driving circuit includes a thin film transistor. An inorganic insulating layer is disposed on the driving circuit. A power supply line is disposed on the inorganic insulating layer, overlaps the driving circuit, and is connected to a common electrode of the display element. An encapsulation substrate is disposed on the power supply line and faces the substrate. A sealing material is interposed between the substrate and the encapsulation substrate and overlaps the driving circuit.
