  • Patent number: 5220446
    Abstract: A method of dispersing spacers and liquid crystal display elements made by the method, capable of lengthening the life of twisted nematic (TN) and super twisted nematic (STN) which require high reliability. Spacers are dispersed on an upper glass substrate, by using air or volatile liquid. Thereafter, an insulation solution is printed on glass substrates having patterned transparent conductive films. Otherwise, spacers are mixed in an insulation solution. Then, the mixture is printed on glass substrates. The obtained liquid crystal element has a construction wherein each spacer is fixed at its opposite sides to oriented layers as well as insulation layers, respectively.
