<p>PURPOSE:To improve the transmittivity when a picture element shutter is open by forming at least one substrate of a pair of parallel substrates of the monomolecular film or cumulative monomercular film of a high-polymer compd. having a hydrophilic part and hydrophobic part in combination within the same molecule. CONSTITUTION:This liquid crystal element is disposed with a pair of the upper substrate 11a and lower substrate 11b which are disposed in parallel with each other and transparent electrodes 12a and 12b wired to the respective substrates. A ferroelectric liquid crystal 13 having the non-spiral structure exhibiting two stable states is disposed between the upper substrate 11a and the lower substrate 11b. Orientation control films 14a and 14b formed of the monomolecular films or cumulative monomercular films of the high-polymer compd. are respectively disposed to the substrates 11a and 11b. The high-polymer compd. constituting the monomolecular films or cumulative monomercular films has the hydrophilic part and hydrophobic part in combination within the molecule thereof. A representative example as the constituting element of the hydrophobic part in general is an alkyl group or unsatd. hydrocarbon group. The orientation control function not possible with the conventional orientation control films is developed by arranging and orienting the molecules having such higher structure in high order.</p> |
