文章简单介绍了几种液晶显示的广视角技术，着重对聚合物稳定液晶垂直取向技术(polymer stabilized vertically aligned，PSVA)进行了概括，包括聚合物稳定液晶垂直取向技术的发展历史、技术优势和研究进展，以及对该项技术的进一步产业化和未来的发展趋势进行预测。与传统的VA器件相比，PSVA改进了器件的电光特性，特别是上升时间，同时不需要MVA器件和PVA器件中在图案电极上的突起物。为了更好地发挥PSVA的技术优势，要优化像素结构以形成稳定的多个液晶指向矢，其次，固化电压、固化强度、固化能量等UV固化条件以及可聚合单体在液晶中的含量需要优化。

In this paper, several wide viewing angle technology used on LCDs have been introduced. Focusing on the polymer stabilized vertically aligned technology, we have give some information on the history and development of this technology. We also predict the futher industrialization as well as the future development trends of the technology. Compared with the traditional VA devices, PSVA is a new type of VA technology which enables the control of the surface pretilt angle of the LC by using a UV curable monomer was introduced. This technique improves the rise time and transmittance and has become a strong contender for future wide-view VA technology. Relatively detailed information was presented on how the electro-optical performance depends on the curing conditions, such as voltage, UV-dosage, and the type of monomers used.
