Abstract
A display device includes a substrate including a display area having sub-pixels and a non-display area adjacent to the display area, an anode electrode disposed in each of the sub-pixels on the substrate, a bank disposed on the anode electrode which is located at a boundary between adjacent sub-pixels, covers a periphery of an upper surface of the anode electrode, and includes a first bank on the anode electrode and a second bank on the first bank, and an organic layer disposed on the anode electrode and the bank and disposed across the sub-pixels.
Claims26
A display device comprising:
- a substrate including a display area including a plurality of sub-pixels, and a non-display area adjacent to the display area;
- an anode electrode disposed in each of the plurality of sub-pixels on the substrate;
- a bank disposed on the anode electrode, located at a boundary between adjacent sub-pixels, covering a periphery of an upper surface of the anode electrode, and including a first bank on the anode electrode and a second bank on the first bank,
- wherein the first bank includes:
- an overlapping portion overlapping the second bank;
- a first exposed portion exposed by the second bank and including a side surface;
- and
- a second exposed portion exposed by the second bank and disposed between the overlapping and the first exposed portion,
- the second exposed portion is provided as a plurality of second exposed portions, and the plurality of second exposed portions that are adjacent are spaced apart from each other in a plan view.
A display device comprising:
- a substrate including a display area including a plurality of sub-pixels including a first sub-pixel, a second sub-pixel, and a third sub-pixel, the substrate further including a non-display area adjacent to the display area;
- an anode electrode disposed in each of the plurality of sub-pixels on the substrate in the display area;
- a bank disposed on the anode electrode, located at a boundary between adjacent sub-pixels, covering a periphery of an upper surface of the anode electrode, and including a first bank on the anode electrode and a second bank on the first bank,
- wherein the first bank includes:
- an overlapping portion overlapping the second bank;
- and
- an exposed portion exposed by the second bank, and
- an outline of the exposed portion has a plurality of bent portions in a plan view.
A display device comprising:
- a substrate including a display area including a plurality of sub-pixels, and a non-display area adjacent to the display area;
- an anode electrode disposed in each of the plurality of sub-pixels on the substrate;
- a bank disposed on the anode electrode, located at a boundary between adjacent sub-pixels, and covering a periphery of an upper surface of the anode electrode;
- an organic layer disposed on the anode electrode and the bank and disposed across the plurality of sub-pixels;
- and
- a protective layer disposed under the organic layer, and including a trench overlapping the bank and passing through the protective layer in a thickness direction.
