Description

【Technical field】 [0001] The present invention relates to a liquid crystal display device, in particular to an in-plane switching (In Plane Switching, IPS) liquid crystal display device. 【Background technique】 [0002] Liquid crystal display device is a kind of flat display device. After decades of development, it not only dominates the application of notebook computers and grows with its growth, but also occupies more and more fields such as monitors. share. The driving force behind its gradual mainstreaming is the improvement of display effect and the drop of price brought about by the remarkable progress of technology. [0003] From simple matrix driving to active matrix driving, the display contrast of liquid crystal display devices has been significantly improved. Many companies have developed related wide-viewing-angle technologies, and the in-plane switching technology is one of them with considerable advantages. Its working principle is that an electric field para...
