Description

【Technical field】 [0001] The invention relates to a liquid crystal display device, in particular to an in-plane switching type liquid crystal display device. 【Background technique】 [0002] The liquid crystal display device is one of the flat display devices. After decades of development, it not only gradually increases in the application of notebook computers, but also occupies an increasing share in fields such as monitors. [0003] From simple matrix driving to active matrix driving, the display contrast of liquid crystal display devices has been significantly improved. At the same time, in order to overcome the defect of narrow viewing angle caused by liquid crystal twisting in the prior art, many companies have developed related wide viewing angle technologies, and In-plane switching (InPlane Switching, IPS) technology is one of the advantages. The principle is: the pixel electrode and the common electrode form a plane electric field, so that the liquid crystal molecul...
