1. A process for producing a liquid crystal display element which comprisesforming 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 β

  • -diketone and nitric acid with an organic solvent, followed by calcination,etching the transparent conductive film to give a first composite having electrodes having desired patterns,performing said forming an electrical insulating metal oxide film step, said forming a transparent conductive film step, and said etching step on a second transparent glass substrate to give a second composite having electrodes having desired patterns,placing the two resulting composites spaced from each other and in parallel so that the electrodes of each composite are positioned at the inner side of the display element and stand opposite to each other, andenclosing a liquid crystal material in the space formed between the two composites.
