LIQUID CRYSTAL DISPLAY DEVICE AND METHOD OF MANUFACTURING THE SAME |
| 摘要 |
An alignment film for liquid crystal display device includes a first portion positioned towards to the liquid crystal layer and a second portion positioned away from the liquid crystal layer. The first portion provides improved anchoring force while the second portion exhibits a lower volume resistance than the first portion. Thus, AC image sticking and DC image sticking can be minimized at the same time. |

1. A liquid crystal display device comprising:
a common electrode and a pixel electrode disposed on one of a first substrate and a second substrate; an alignment film on each of the first substrate and the second substrate; and a negative dielectric anisotropy liquid crystal layer disposed between the alignment film of the first and second substrates, wherein the alignment film on at least one of the substrates has a polyimide chain with a molecular weight of 100,000 Da or more. |
