Abstract
The liquid crystal apparatus has a segment substrate and a common substrate. Segment electrodes are formed on the segment substrate, while common electrodes are formed on the common substrate. A liquid crystal composition is sealed between the segment and common substrates with a seal member. The segment and common electrodes, the liquid crystal composition and the seal member constitute an elongated shatter portion including light shutters arranged in two rows. Liquid crystal reservoir portions are formed between the substrates and coupled to the shutter portion. The liquid crystal reservoir portions are resilient and thus can be deformed to suppress a change in the pressure applied on the liquid crystal composition due to a change in the volume of the liquid crystal composition. As a result, the formation of bubbles in the shutter portion can be prevented.
