Abstract
In a liquid crystal display element having a twisted structure wherein the periphery of two transparent glass substrates having electrodes according to desired display patterns is sealed with a sealing medium and a liquid crystal is enclosed in the space thus produced, the one characterized by having an undercoating film of metal oxide on the inner surface of each glass substrate, having a transparent electrode on each undercoating film of metal oxide and having an orientation controlling film made from an organic polymer and having abrasion grooves along a certain direction on each electrode can give a liquid crystal display element excellent in heat resistance of the orientation controlling film, excellent in adhesion to the glass substrates, and the like without causing a voltage drop, or without damaging rising of voltage-brightness property and response property.
