Disclosed is a display device including a base layer, a circuit layer including a plurality of transistors spaced apart from each other and disposed on a top of the base layer, a plurality of insulating layers disposed on a top of the base layer, and a plurality of contact electrodes electrically connected to the transistors, respectively, a first light emitting unit disposed on a top of the circuit layer, a second light emitting unit, and a lower protrusion disposed between at least one of the transistors and the second lower electrode, wherein at least one of the contact electrodes is disposed to extend to a top surface of the lower protrusion in the circuit layer while following a shape of the lower protrusion to simplify an etching process of an encapsulation layer.

Display device

A display device includes: a substrate on which a pixel area for displaying an image and a transmission area for transmitting an external light are defined; a transistor disposed on the substrate in the pixel area; a first electrode disposed on the transistor in the pixel area and electrically connected to the transistor; a pixel defining layer exposing at least a portion of the first electrode; an emission layer disposed on the first electrode in the pixel area; a surface control layer disposed on the substrate in the transmission area; at least one dam disposed between the pixel area and the transmission area and surrounding the surface control layer; and a second electrode disposed on the emission layer.

Display device having surface control layer in transmission area

A display panel includes an emitting part including a light emitting element and a transmitting part adjacent to the emitting part and including a low adhesion part including a carbon compound. The low adhesion pattern includes fluorine (F).

Display panel, display apparatus including the same, and method for manufacturing the display panel

A display apparatus of an embodiment includes a first area and a second area disposed adjacent to the first area in a plan view, and includes a first electrode disposed in the first area and a second electrode disposed in the second area, a hole transport region disposed on the first electrode and the second electrode, an emission layer disposed on the hole transport region to overlap the first electrode and not to overlap the second electrode, a buffer layer disposed on the emission layer in the first area and the second area, a surface energy controlling layer disposed on the buffer layer to overlap the second electrode and not to overlap the first electrode, and a third electrode disposed on the buffer layer to overlap the first electrode and not to overlap the surface energy controlling layer. Such a display apparatus may have improved transmittance.
