ABSTRACT:
In an electro-optical element comprising a liquid crystal, such as a smectic liquid crystal, sealed between two substrates arranged to confront each other with a space of an order of .mu.m, if spacer particles for regulating the space between the substrates and phenol type curing agent-incorporated epoxy resin adhesive particles for moderating stresses generated by distortions or warps of the substrates are arranged in the space between the substrates, a minute uniform space, especially a uniform space of 1 to 3 .mu.m effective for a ferroelectric liquid crystal, can be maintained between the substrates. In this structure, alignmental films are not disturbed at all. Furthermore, even if a nematic or super-twist liquid crystal is used, a uniform space can be stably maintained between the substrates.
