Polarizer, color film substrate, display panel and display device

Abstract

The invention discloses a polarizer, a color film substrate, a display panel and a display device. According to the invention, the static electricity on the color film substrate can be guided and brought away through the polarizer, so that a conductive layer arranged on the color film substrate can be omitted. The quality of a product is improved. The polarizer comprises a transparent conductive film layer. Through the transparent conductive film layer, the polarizer has the conductive function and the static electricity on the color film substrate can be guided and brought away. As a result,the conductive layer arranged on the color film substrate can be omitted, so that the product has the anti-ESD capability. In addition, the process of manufacturing the silver adhesive in the prior art is not needed, so that the abnormity, the oxidization and the breakage of the silver adhesive during the coating process are avoided. Meanwhile, since no silver adhesive is manufactured, the phenomenon that the silver adhesive permeates into the interior of the panel can be avoided. Therefore, the display effect of the product can be guaranteed, and the quality of the product is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a polarizer, a color filter substrate, a display panel and a display device. Background technique [0002] For Advanced Super Dimension Switch (ADS) products, due to electrostatic interaction, the surface of the Thin Film Transistor-Liquid Crystal Display (TFT-LCD) panel will accumulate charges, which will affect the panel The internal electric field will affect the display effect of the product, and even cause a series of defects, such as greening of the screen, breakdown of the gate drive circuit (Gate on Array, GOA), etc., which seriously affect the quality of the product. In order to solve this problem, such as figure 1 As shown, the current ADS and HADS (High Transmittance-Advanced Ultra-Dimensional Field Switching) products will coat a conductive layer (Back ITO) 102 on the back of the color filter 103 (or color filter) of the color filter substrate to act as An...

Problems solved by technology

However, this design will increase the process of dispensing silver glue on the module, and there will be abnormalities in the coating process of the silver glue. Many problems such as silver glue oxidation, breakage, and penetration into the panel will reduce the display effect of the product and even seriously affect the product quality.

And for the current Touch products, when there is Back ITO on the color filter substrate, it will cause the process of removing the Back ITO when the Touch product is attached later, but if the Back ITO is not added to the color filter side, it will make the subsequent products resistant. Decreased ESD capability
