Abstract
A liquid crystal display element is produced by forming an electrical insulating metal oxide film on a transparent glass substrate, forming a transparent conductive film thereon by coating a coating solution prepared by diluting a solute comprising indium, tin, a .beta.-diketone and nitric acid with an organic solvent, followed by calcination, etching the transparent conductive film to give electrodes having desired patterns, placing the two resulting glass substrates in parallel so that individual electrodes at the inner side stand opposite to each other, and enclosing a liquid crystal material in the space formed between the two glass substrates. The liquid crystal display element thus produced has transparent electrodes which have low sheet resistance, enhanced mechanical strength and strong adhesive strength to the glass substrate.
