COATING SOLUTION FOR FORMING TRANSPARENT ELECTRICALLY CONDUCTIVE FILM, METHOD OF PREPARATION THEREOF, ELECTRICALLY CONDUCTIVE SUBSTRATE, METHOD OF PREPARATION THEREOF, AND DISPLAY DEVICE HAVING TRANSPARENT ELECTRICALLY CONDUCTIVE SUBSTRATE.

摘要

An electrically conductive substrate has on the surface thereof a transparent conductive film made from a coating solution that is obtained by dispersing or dissolving in the water and/or an organic solvent a matrix composed of electrically conductive particles having: (a) an average particles diameter of smaller than 500 ANGSTROM ; (b) the particles of smaller than 600 ANGSTROM being contained in an amount of greater than 60 % by weight; (c) the particles of smaller than 100 ANGSTROM being contained in an amount of greater than 5 % by weight; (d) the particles of greater than 1000 ANGSTROM being contained in an amount of smaller than 15 % by weight; and a silica polymer having: (A) an average polymerization degree of 1,500 to 10,000; (B) the polymer with a polymerization degree of smaller than 3,000 being contained in an amount of smaller than 50 % by weight; (C) the polymer with a polymerization degree of greater than 10,000 being contained in an amount of smaller than 20 % by weight. The electrically conductive substrate has excellent adhering property, surface smoothness, durability and transparency. The display device having a transparent electrically conductive substrate on a display panel portion exhibits excellent resolution and offers vivid image at all times.
