Abstract

An organic light-emitting display apparatus, including: a first electrode disposed on the substrate; a pixel defining layer covering an edge of the first electrode; a residual layer disposed on the first electrode and the pixel defining layer, the residual layer comprising a fluoropolymer; a first organic functional layer comprising a first light emitting layer disposed on the residual layer on the first electrode; and a second electrode disposed on the first organic functional layer.

First claim

What is claimed is:

1 . An organic light-emitting display apparatus, comprising:
a first electrode disposed on the substrate; a pixel defining layer covering an edge of the first electrode; a residual layer disposed on the first electrode and the pixel defining layer, the residual layer comprising a fluoropolymer; a first organic functional layer comprising a first light emitting layer disposed on the residual layer on the first electrode; and a second electrode disposed on the first organic functional layer.

2 . The organic light-emitting display apparatus of claim 1 , wherein the fluoropolymer has a fluorine content in a range of about 20˜60 wt %.

3 . The organic light-emitting display apparatus of claim 1 , wherein the fluoropolymer comprises at least one of polytetrafluoroethylene, polychlorotrifluoroethylene, polydichlorodifluoroethylene, a copolymer of chlorotrifluoroethylene and dichlorodifluoroethylene, a copolymer of tetrafluoroethylene and perfluoroalkylvinylether, a copolymer of chlorotrifluoroethylene and perfluoroalkylvinylether, a copolymer of tetrafluoroethylene and perfluoroalkylvinylether, and a copolymer of chlorotrifluoroethylene and perfluoroalkylvinylether.

4 . The organic light-emitting display apparatus of claim 1 , wherein a thickness of the residual layer is equal to or greater than about 0.5 nm and equal to or less than about 5 nm.

5 . The organic light-emitting display apparatus of claim 1 , wherein the organic functional layer comprises at least one functional layer of a hole injection layer, a hole transport layer, an electro transport layer, and an electron injection layer.

6 . An organic light-emitting display apparatus, comprising:
a first first electrode disposed on the substrate; a second first electrode disposed separate from the first first electrode; a pixel defining layer covering an edge of the first first electrode and the second first electrode; a residual layer disposed on the first first electrode, the second first electrode and the pixel defining layer, the residual layer comprising a fluoropolymer; a first organic functional layer comprising a first light emitting layer disposed on the residual layer on the first first electrode; a second organic functional layer comprising a second light emitting layer disposed on the residual layer on the second first electrode; and a second electrode commonly disposed on the first organic functional layer and second organic functional layer.

7 . The organic light-emitting display apparatus of claim 6 , wherein a first color of light emitted from the first light emitting layer is different from a second color of light emitted from the second light emitting layer.

8 . The organic light-emitting display apparatus of claim 6 , further comprising;
a first auxiliary cathode disposed between the first organic functional layer and the second electrode; and a second auxiliary cathode disposed between the second organic functional layer and the second electrode.

9 . The organic light-emitting display apparatus of claim 8 , wherein the first auxiliary cathode and the second auxiliary cathode directly contact the second electrode.

10 . The organic light-emitting display apparatus of claim 6 , wherein the second electrode is integrally disposed on the first organic functional layer and second organic functional layer.
