PURPOSE: To produce the liquid crystal device having a large pretilt angle and to improve the reliability and quality of the device by executing a heat treatment in a vacuum or inert gaseous atmosphere, thereby preventing the deterioration in the orientation regulation power imparted to an orientation control film.

CONSTITUTION: Bead spacers 16 (silica beads, alumina beads, etc.) having about 1.5μm average grain size are sprayed onto one glass substrate 11a (11b) of glass substrates 11a, 11b and a sealing adhesive 17 which is an adhesive of an epoxy resin is formed by a screen printing method on another glass substrate 11b (11a). Two sheets of these glass substrates 11a, 11b are held to face each other at 0.1 to 3μm spacing and are subjected to a heat treatment to solidify the sealing adhesive 17. The heat treatment is executed in a vacuum or inert gaseous atmosphere in such a case. As a result, the orientation control film is less deteriorated than in the case of execution of the heat treatment in the atm. and the degradation in the pretilt angle is suppressed.
