Abstract
A display device according to an example embodiment of the present disclosure includes a substrate having a plurality of sub-pixels defined thereon, a bank disposed between the plurality of sub-pixels, at least one trench pattern disposed between the plurality of sub-pixels and from which a thickness of an upper surface of the bank is partially removed, a buffer layer on the bank, the buffer layer being deposited to cover an inner surface of the trench pattern by an initiated chemical vapor deposition (iCVD) method and an encapsulation layer disposed on the buffer layer. Therefore, it is possible to improve reliability by preventing film formation defects of the encapsulation layer in the trench, and to improve display quality by preventing display quality defects such as light and dark spots and bright spots.

A display device, comprising:
- a substrate having a plurality of sub-pixels defined thereon;
- a bank disposed between the plurality of sub-pixels;
- at least one trench pattern disposed between the plurality of sub-pixels and from which a thickness of an upper surface of the bank is partially removed;
- a buffer layer on the bank, the buffer layer being deposited to cover an inner surface of the trench pattern by an initiated chemical vapor deposition (iCVD) method;
- and
- an encapsulation layer disposed on the buffer layer.
A display device, comprising:
- a substrate having a plurality of sub-pixels defined thereon;
- a bank disposed between the plurality of sub-pixels;
- at least one trench pattern disposed between the plurality of sub-pixels and from which a thickness of an upper surface of the bank is partially removed;
- at least one spacer disposed on the bank between the plurality of sub-pixels;
- a buffer layer deposited on an inner surface of the trench pattern and the bank and the spacer along an inner shape of the trench pattern and a bending of the spacer by an initiated chemical vapor deposition (iCVD) method;
- and
- an encapsulation layer disposed on the buffer layer.
A display device, comprising:
- a plurality of sub-pixels disposed above a substrate;
- a bank disposed above the substrate;
- at least one trench pattern formed in the bank and between the plurality of sub-pixels;
- a buffer layer formed within the at least one trench pattern via application of an anisotropic chemical vapor deposition method;
- and
- an encapsulation layer disposed above the buffer layer.
