Description

液晶面板的液晶介质 技术领域
本发明是有关于一种液晶面板的液晶层，特别是有关于一种液晶面板的液晶介质，其可改进液晶屏幕中影像残留（Image sticking）现象的问题。
 背景技术
在液晶显示面板的制造过程中，图像垂直调整技术(Patterned Vertical Alignment, PVA)模式液晶显示面板或广域垂直液晶队列(High Vertical Alignment, HVA)模式液晶显示面板的液晶层内难以避免地会存在一些残留的可聚合化合物，其键结于稀释剂液晶分子的烯基上。所述可聚合化合物为液晶活性单体(Reactive Monomer，RM)。在长时间驱动后，带电荷的可聚合化合物的劣化会产生带电离子，而后这些带电荷的可聚合化合物和带电离子的分布状况会逐渐产生变化，进而造成液晶显示面板的显示质量的劣化。
具体而言，在长时间驱动过程中，液晶层内所述带电荷的可聚合化合物和带电离子会依据其极性(Polarity)而产生分离的现象，而这些依照极性分离后的所述带电荷的可聚合化合物和带电离子会消耗一部份施加于液晶层的偏压(Bias voltage)，使得作用于液晶层上的偏压产生变异(Variation)，此现象称为屏蔽效应(Screen effect)。除此之外，这些依照极性分离后的带电荷的可聚合化合物和带电离子会于液晶显示面板中产生一寄生电位(Parasitic potential)，进而导致共享电压的飘移(V-com shift)。
承上所述，由于液晶层内带电荷的可聚合化合物和带电离子会导致屏蔽效应以及共享电压的飘移，因此，液晶显示面板在显示时会出现残影现象(或称面型影像残留)，造成显示质量恶化。因此，有必要提供一种掺入于液晶混合物中可以改进影像残留的液晶化合物，来解决现有技术所存在的问题。
 技术问题
本发明的主要目的在于提供一种液晶面板的液晶介质。通过将基于并四苯衍生物（Tetracene derivative）的液晶化合物掺入于液晶混合物中让所述基于并四苯衍生物的液晶化合物键结于稀释剂液晶分子的烯基上，以防止稀释剂液晶分子的烯基与可聚合化合物发生反应，从而抑制了稀释剂液晶分子的烯基与可聚合化合物的键结。本发明可以改进可聚合化合物键结于稀释剂液晶分子的烯基所产生的影像残留的问题。
