Abstract
Abstract A transparent electroconductive laminate having a transparent electroconductive layer composed mainly of indium oxide deposited on a transparent planar substrate, the electroconductive layer comprises two uniformly mixed phases comprising a crystalline phase of 1-80% by area and an amorphous phase of 99-20% by area and, in particular, the crystalline phase is composed of a grain or grains having a size of less than 1 mu m and the crystal grain or grains are in at least one of an isolated state, a linked state and a state in which the crystal grain or grains are separated from each other by a network of the amorphous phase, whereby the laminate is suitable for an electrode of a transparent touch panel and an electroluminescent panel.
