In the production process of the liquid crystal panel, due to a series of manufacturing processes (such as film deposition, dry etching, polarizer attachment and the like) and substrate transportation, a lot of static charges are accumulated on the surface of the glass substrate, if the static charges cannot be released, when the static charges are accumulated to a certain degree and are randomly discharged, the structures of partial circuits or the structures of liquid crystal particles are damaged, poor display is caused, and an improvement space exists.
A Color Filter (CF) in the chinese language of conventional design is used for a liquid crystal display device to perform color display, and a transparent electrode (also called an ITO transparent conductive layer) is disposed below a glass substrate (with a display surface facing upward), and the others are resin layers, and are hardly conductive. During production or use, static electricity is conducted through the transparent electrode and is preferentially released at uneven positions or positions with tips on the side of the color filter.
In the production process, before the color filter and the thin film transistor substrate (TFT) are assembled (as shown in fig. 1), the display area is uneven due to the existence of the color unit of the color filter, and static electricity is easily released in the display area to damage the circuit or the color unit of the display area, thereby causing poor display.
In the production process or the use process, when the Color Filter (CF) is assembled with the thin film transistor substrate (as shown in fig. 2), the thin film transistor substrate (TFT) side is provided with the wiring, so that a protrusion mechanism exists, and when external static electricity is transmitted to the Color Filter (CF), the static electricity is easily released between the Color Filter (CF) protrusion and the thin film transistor substrate (TFT) protrusion, so that the upper plate and the lower plate are short-circuited.
The electrostatic discharge protection device of CN200710170938.8 liquid crystal display and the manufacturing method thereof have noticed the problem of electrostatic discharge, but the design thereof can only deal with the problem of electrostatic discharge during the use process, and cannot deal with the problem of electrostatic discharge during the panel assembly process, there is room for improvement, and there is room for improvement due to its higher cost, and there is room for improvement due to its complex production process.
