Problems solved by technology

[0002] At present, the problem of poor antistatic performance of the liquid crystal screen itself is basically improved by doping the liquid crystal with an antistatic agent. Ion channels are formed under the electric field to guide away the residual charge. The antistatic performance of this antistatic agent will gradually decrease or even disappear with time and high temperature because the antistatic agent is easy to combine with the PI guide film or frame glue in the box, making it even more difficult What is worrying is that the antistatic agent exists in the form of impurities in the liquid crystal, and black shadows often appear at high temperatures, which cannot meet the needs of customers.

Abstract

The invention discloses a liquid crystal display with excellent antistatic performance and a manufacturing method thereof. The liquid crystal display comprises double-faced ITO glass, a frame, bottom ITO glass and bottom polaroid. A liquid crystal is arranged in the space formed by the double-faced ITO glass, the frame and the bottom ITO glass. The double-faced glass comprises face glass, a first ITO conductive layer arranged on the surface of the face glass and a second ITO conductive layer arranged on the lower surface of the face glass and etched with a first ITO pattern. The bottom ITO glass comprises bottom glass and a third ITO conductive layer arranged on the upper surface of the bottom glass and etched with a second ITO pattern. A polaroid is arranged in a vision area on the upper part of the first ITO conductive layer. A piece of conductive cloth is arranged outside the vision area of the upper part of the first ITO conductive layer and is connected with a static electricity lead-out device. According to the invention, via the 8KV discharge, there is no static electricity left in the LCD; the antistatic performance of the product is stable; and service lifetime of the product can reach 100000 hours.
