摘要:
A ferroelectric liquid crystal device (81) has transparent plates (83a, 83b), on which transparent electrodes (85a, 85b) are formed, arranged opposed to each other to form a space therebetween, with ferroelectric liquid crystals (95) sealed in the space. Black masks (89b) are arranged between the transparent electrodes (85b). Portions of the black masks (89b) extend over the transparent electrodes (85b). Black masks (89a) are arranged between the transparent electrodes (85a), with portions of the black masks (89a) extending over the transparent electrodes (85a). Since black masks (89a, 89b) are provided between the transparent electrodes (85a, 85b), respectively, state of display can be made uniform in non-pixel portions. Since the black masks (89a, 89b) on the transparent electrodes (85a, 85b) prevents undesired inversion of spontaneous polarization of the liquid crystal molecules in the pixel portions, the state of display of the pixel portions can be made stable.
