Abstract
A display device and a method of manufacturing the same are disclosed. The display device comprises a thin film transistor on a substrate, a protective film on the thin film transistor, and an alignment film on the protective film. The protective film includes one or more protective films, and a protective film adjacent to the alignment film among the one or more protective films has a silicon content higher than a nitrogen content. Thus, it is possible to provide a display device capable of reducing image sticking or flicker.
Claims23
A display device, comprising:
- a thin film transistor on a substrate;
- a protective film on the thin film transistor;
- and
- an alignment film on the protective film,
- wherein the protective film includes at least one protective film, the protective film adjacent to the alignment film among the at least one protective film has a non-zero silicon content and a non-zero nitrogen content, and the silicon content is higher than the nitrogen content,
- wherein the protective film adjacent to the alignment film has a lower volume resistance than a volume resistance of the alignment film.
A display device, comprising:
- a pixel electrode and a common electrode on at least one of a first substrate and a second substrate;
- a first alignment film and a second alignment film on the first substrate and the second substrate, respectively;
- a liquid crystal layer between the first substrate and the second substrate, the liquid crystal layer having negative dielectric anisotropy;
- and
- a protective film adjacent to the liquid crystal layer, the protective film having a lower volume resistance than a volume resistance of the first alignment film,
- wherein the protective film is formed of a silicon nitride and a bonding ratio of silicon and nitrogen in the protective film is 1 or less.
