Title:
COATING COMPOSITION, ELECTROCONDUCTIVE FILM, AND LIQUID CRYSTAL DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2019/176140
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a coating composition and an electroconductive film, capable of improving touch panel performance, such as operational stability over time and touch detection sensitivity of a liquid crystal display panel having a reduced thickness. This problem is solved by a coating composition comprising chain-like electroconductive inorganic particles, a binder, a high-boiling-point solvent, and a low-boiling-point solvent, wherein: the contained amount of the chain-like electroconductive inorganic particles with respect to the total amount of the chain-like electroconductive inorganic particles and the binder is 30-90 mass%; the binder is an alkoxysilane having a weight-average molecular weight of 1,000-20,000; and said coating composition is intended to be used in a liquid crystal display panel that has a TFT array substrate, touch detection electrodes, a liquid crystal layer, and a color filter substrate in order to form an electroconductive film on a base material surface of said color filter substrate on the opposite side of the liquid crystal layer.
