Title: Production of liquid crystal display element
Inventor: HAMA HIDEO
IPC: G02F1/1337
Filed: 1987-11-30
Abstract: PURPOSE:To orient the liquid crystal molecules of a ferroelectric liquid crystal having a smectic A phase in a high-temp. part uniformly over the large area by impressing an electric field simultaneously with a magnetic field to the liquid crystal during slow cooling from the isotropic state to a ferroelectric liquid crystal phase after a weak rubbing treatment. CONSTITUTION:A high-polymer film is formed on a substrate of a liquid crystal panel and is subjected to the weak rubbing treatment to the extent that the liquid crystal cannot be uniformly oriented by said treatment alone. The liquid crystal is simultaneously heated to the isotropic state and thereafter the ferroelectric liquid crystal is slowly cooled to the ferroelectric liquid crystal phase from the isotropic state. The magnetic field and the electric field are simultaneously impressed to the liquid crystal in this slow cooling period. The liquid crystal to which this method is most effectively applied is the liquid crystal having a phase transfer system which attains the ferroelectric liquid crystal phase by way of a cholesteric phase and smectic A phase upon falling of the temp. from the isotropic liquid phase. Not only the magnetic field but also the electric field are applied to the liquid crystal in the process of slow cooling to the ferroelectric phase. Spirals are unraveled by the torque from the impressed electric field in the cholesteric phase and, therefore, the liquid crystal is uniformly oriented to the large area.
