ABSTRACT:
A portable information apparatus has a film liquid crystal device having a pair of flexible substrates spaced apart from one another to define therebetween a gap containing liquid crystal, first surface portions having a curved cross-section, engagement portions extending from respective ones of the first surface portions, and at least one second surface portion having a planar cross-section. An injection port is formed in the at least one second surface portion and through which the liquid crystal is injected into the gap. A sealing portion is disposed on the at least one second surface portion for sealing the injection port. A holding structure has a first holding member and a second holding member for holding the film liquid crystal device in a curved state while the at least one second surface portion of the film liquid crystal device remains planar in cross-section and while the first holding member engages the engagement portions of the liquid crystal device.
