Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a liquid crystal cell which is easily rotated and moved in a prescribed axial direction, to provide a projection lens structure for a liquid crystal projector, which can be easily moved in a prescribed axial direction, and to provide a video projection device using the structure. SOLUTION: The liquid crystal cell, the projection lens structure, and the video projection device using the structure are constituted so that the liquid crystal cell and a projection lens can easily be controlled for accurate focusing.
