Life of the patent
14 dated eventsAbstract
Liquid crystal material is interposed between an upper panel and a lower panel. The lower panel includes signal transmitting wires including a gate wire and a data wire, thin film transistors connected to the signal transmitting wires and pixel electrodes connected to the thin film transistors, and the upper panel includes color filters, a black matrix and a common electrode. The pixel electrodes and the common electrode have apertures partitioning the pixel electrode into several domains. In addition, the director of liquid crystal molecules contained in the liquid crystal material is aligned perpendicular to the upper panel and the lower panel in absence of electric field between the pixel electrodes and the common electrode. The dielectric anisotropy of the liquid crystal material has a value ranging −4.0 to −5.5.
