Liquid crystal cell with bubble traps

Abstract

Abstract The liquid crystal cell (2) comprises a space divided by a separating wall (18) into a main chamber (15) and a secondary chamber (16) which define respectively an active surface and a passive surface. The secondary chamber is partially filled by the liquid crystal (8) and by a gas (17). According to the invention, the cell further comprises means for compensating variations of volume of the liquid crystal, which means are constituted by a secondary chamber (16) divided into a plurality of compartments, a plurality of openings of passages (20) being formed in the separating wall (18) in order that the main chamber (15) and the secondary chamber should communicate with one another. <IMAGE>
