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.
