PURPOSE:To obtain sufficient memory performance, steep threshold value characteristics, high contrast, and fast optical response by heating an orienting film part above its glass transition point in the manufacturing process of the panel and erasing rubbing effect. CONSTITUTION:The manufacturing process wherein ferroelectric liquid crystal is used and an organic high polymer is used for the orienting film is provided with a process wherein a liquid crystal part is heated above the glass transition point of a high polymer constituting the orienting film part after a liquid crystal injecting process while a liquid crystal part is held above its transparency point and above its fusion point and a process wherein the panel is cooled thereafter. Here, when the orienting film is heated above its glass dislocation point, the temperature of the liquid crystal is held in the range of smectic A phase specially. For this temperature control, electric heating to a conductor layer provided between the orienting film in, for example, the panel and the transparent substrate is used in addition to external heating by a normal thermostatic chamber. Consequently, the sufficient memory performance, steep threshold value characteristics, high contrast, and high optical response are obtained. |
