摘要 <p>Provided is a projection video display device with which a sliding load is minimized while maintaining an adjustment precision in a lens shift mechanism. A lens shift mechanism (32) which moves a projection lens in a direction which is orthogonal to the optical axis of projected light has a configuration in which mobile bases (50, 60), which retain the projection lens, slide using a shaft (52), which is attached on a fixed member (4) side, as a guide member. A further aspect of the configuration is that a correction screw is inserted from the rear face side of the fixed member (4) to make contact with the shaft (52), and optical axis tilt and misalignment of the projection lens are corrected by adjusting the degree of insertion of the correction screw.</p>
