ABSTRACT:
A first electrode plate and a second electrode plate are overlapped on each other with a seal member and spacer walls interposed therebetween. The cell gap formed between both plates is filled with liquid crystal such as smectic liquid crystal. To eliminate orientation disturbance of the liquid crystal caused in the filling process, the liquid crystal flow coming from the down stream of the display area through passages outside the display area (turn-around flow) is eliminated. Dam walls for preventing the liquid crystal flow through the outer passages or structures for reducing the flow speed are formed in the outer passages. Alternatively, the filling passages in the display area are separated from the outer passages. Thus, the liquid crystal is correctly oriented in the display area, thereby achieving uniformity of images displayed.
