COATING LIQUID FOR FORMING TRANSPARENT FILM, SUBSTRATE HAVING TRANSPARENT COATING FILM AND DISPLAY DEVICE

摘要

PURPOSE: To provide a coating liquid for forming a transparent coating film having improved film strength and conductivity without causing cracking in the formation of the film and, when a conductive layer is formed as a lower layer, causing uniform shrinkage including the conductive layer to prevent the generation of cracks and provide a substrate having transparent conductive coating layer produced by using the coating liquid and a display device provided with the substrate. CONSTITUTION: The coating liquid for forming a transparent coating film contains a matrix precursor composed of (i) a hydrolyzed product of a tetraalkoxysilane and (ii) a hydrolyzed product of an organic silicon compound having one or more functional groups selected from epoxy group, acrylic group and vinyl group. The ratio of the component (ii) in the matrix precursor is 0.5-50 wt.%. The matrix precursor is produced by the simultaneous hydrolysis of a mixture of the tetraalkoxysilane and the organic silicon compound having one or more functional groups selected from epoxy group, acrylic group and vinyl group.
