摘要:
A liquid crystal display including upper and lower substrates facing each other, electrodes and alignment layers sequentially disposed on and between the upper and lower substrates, a liquid crystal layer interposed between the alignment layers, and a spacer for controlling the distance between the upper and lower substrates, wherein an ion-absorbing material layer coats the spacer. Since an adverse phenomenon caused by generation of ions or contaminants in a liquid crystal cell is prevented, the reliability of the liquid crystal display is improved. Blurriness is prevented from occurring on a displayed picture due to a change in the alignment characteristic of the liquid crystal material. Also, crosstalk and deterioration of contrast are prevented by suppressing a decrease in the specific resistance of the liquid crystal material.
摘要:
An optical alignment polymer and an optical alignment composition having the same are provided. The optical alignment polymer has a compound selected from the group consisting of poly(maleimide), poly(vinyl acetal), poly(phenylene oxide), poly(maleimide styrene) and their derivatives in its main chain, and a photosensitive group at its side chain. The optical alignment polymer can have high level of optical alignment performance and high thermal stability.
摘要:
An optical alignment composition, an alignment layer formed using the same with an excellent liquid crystal alignment property, and an LCD having the alignment layer are provided. The optical alignment composition having excellent thermal stability and alignment property and an alignment layer can be obtained while adopting a non-destructive optical alignment method. Accordingly, an LCD with improved performance can be obtained.
