发明名称 Liquid crystal display element and process for production thereof.
摘要 <p>This invention relates to a liquid crystal display element comprising a pair of transparent substrates (1a, 1b), electrodes formed on the individual surfaces thereof facing each other, a liquid crystal material layer held between the substrates (1a, 1b), and gap controlling material (2, 3) for keeping the gab (1g) between the substrates (la, lb), whereby the gap controlling material is dispersed and fixed on the substrate surface by an insulating coating film (4) such as an orientation controlling film. When the gap controlling material (2, 3) is thus dispersed and fixed, there can be obtained a liquid crystal display element in which the distance (1g) between the substrates is uniform. Preferably the gap controlling material is a combination of a polymer solid (3) and an insulating material (2) having a higher softening point and rigidity than those of the polymer solid (3), and the insulating coating film (4) is an orientation controlling film.</p>
