The present disclosure relates to a display panel. More specifically, the display panel is configured to surround an opening area, includes a reflective electrode including an inclined surface, and therefore provides increased luminous efficiency.

Display panel

Discussed is a touch display device that can include a substrate including an active area and a non-active area, a transistor disposed on the substrate, a sub-pixel electrically connected to the transistor, and including an organic light emitting diode, an encapsulation layer disposed on the organic light emitting diode, a planarization layer disposed on the encapsulation layer, and a plurality of touch electrodes disposed between the encapsulation layer and the planarization layer, the plurality of touch electrodes including an open area. The planarization layer can include a thickness variation at the open area of the plurality of touch electrodes.

Touch display device

A display panel and an organic light emitting display device with enhanced light extraction efficiency is described. The display panel and the display device include an insulating film including at least one concave portion, a first electrode disposed to cover the concave portion, a bank including a first part on the first electrode and overlapping a part of the flat portion of the concave portion, a second part extending from the first part and overlapping an inclined portion of the concave portion, and a third part extending from the second part and disposed on the side portion, an organic layer overlapping the concave portion, and a second electrode on the organic layer and the bank. A width of the first part of the bank is wider than a width of the second part of the bank. Thus, it is possible to provide a display device with enhanced light extraction efficiency.

Organic light emitting display panel and organic light emitting display device including the same

A display device, such an organic light emitting display device is disclosed. The display device includes an insulating film including a concave portion in an area of at least one subpixel, a first electrode on a side portion of the concave portion and on the concave portion in an area of the subpixel, an organic layer overlapping the concave portion and on the first electrode. An organic layer disposed in the at least one blue subpixel may include at least one of a first light emitting dopant with a maximum emission wavelength of 457 nm or less, a second light emitting dopant with a full width at half maximum (FWHM) of 30 nm or less, and/or a third light emitting dopant with the maximum emission wavelength of 457 nm or less and the full width at half maximum of 30 nm or less. Thus, a display device with enhanced light extraction efficiency is provided.

A touch display device can include a substrate including an active area and a non-active area, a transistor disposed on the substrate, a sub-pixel electrically connected to the transistor and including an organic light emitting diode, an encapsulation layer disposed on the organic light emitting diode, a planarization layer disposed on the encapsulation layer and including a lens unit, and a plurality of touch electrodes disposed between the encapsulation layer and the planarization layer. The plurality of touch electrodes can include an open area. Further, the lens unit can be disposed in the open area of the plurality of touch electrodes.

Embodiments of the present disclosure relate to a touch display device, and more particularly, provide a touch display device with improved brightness owing to including an insulating film having a concave portion and a planarization layer having a microlens unit.
