ABSTRACT:
In a twisted nematic type liquid crystal display element wherein two electrode substrates, in which an electrode having desired patterns and an orientation controlling film for facilitating the orientation of liquid crystal molecules along a given direction are disposed in this order on the inner surface of each transparent substrate such as glass, are placed in parallel with a certain distance, the periphery of the transparent substrates are sealed with a sealing medium, and a nematic liquid crystal is enclosed in the space thus produced, the one characterized by using as the orientation controlling film a film of polymer having imide rings and as the sealing medium a calcined glass having a low melting point obtained by adding 1 to 5 parts by weight of either SiO.sub.2 or Al.sub.2 O.sub.3 or both of SiO.sub.2 and Al.sub.2 O.sub.3 to 100 parts by weight of a composition comprising:
