Abstract: PURPOSE: To provide a normally displaying part with the same dispaly system as that of the display of the main display part by differing the orientation direction of liquid crystals with the normally displaying parts and other display parts.  
     CONSTITUTION: After the substrates 5, 6 having electrodes 8 for main display and a counter electrode 9 are subjected to homeotropic-orientating treatment, the normally displaying parts and sealed parts are masked and are subjected to twist orientation treatment. If the polarization directions of the polarizing plates 10, 11 grasping the liquid crystal cell therebetween are made parallel, the normally displaying parts having undergone the homeotropic orientation appear bright and the other parts having undergone the twist orientation appear dark. If voltage is applied to the ekectrodes 8, 9, the liquid crystal of said parts assume homeotropic orientation and becomes bright. After all, the displaying in which the normally displaying parts are always bright and the other display parts are of the same brightness as that of the normally displaying parts only in the positions where no voltage is applied may be performed under the dark background.
