Liquid crystal electro-optical element and process for preparation thereof

A process for the preparation of a liquid crystal electro-optical element comprising a liquid crystal, two substrates secured by a sealing material to confront each other with a certain space and hold the liquid crystal therebetween, alignmental films present in interfaces between the liquid crystal and the substrates to line up molecules of the liquid crystal and the driving means for applying a voltage to the molecules of the liquid crystal, said process comprising the steps of arranging the sealing material on one substrate having an electrode and alignmental film on the surface thereof in a peripheral edge portion thereof on the alignmental film side, dispersing and arranging spacer particles having a diameter equal to an intended space length and adhesive particles comprising as the main component a partially amine cured epoxy resin containing a phenolic latent curing agent which is compatible with the epoxy resin, the adhesive particles having a particle size larger than the diameter of the spacer particles, on the surface of one substrate, bonding the two substrates by, heat-pressing the substrates in the piled state, and sealing the liquid crystal in the space between the substrates.
