Abstract
In a projection type picture display apparatus, three degrees of freedom out of six degrees of freedom which are adjusted by an angle-of-view adjusting mechanism are adjusted by using one adjusting plate (three-axis adjusting plate). The adjusting plate on which a projection unit is fixedly supported rotates the projection unit around the X-axis or Z-axis with respect to a screen disposed in parallel to the XY plane and translates the projection unit in the Y-axis direction to adjust three degrees of freedom. The adjusting plate has first, second and third support shafts extending in the Y-axis direction, a first adjusting shaft engageable with the first and second support shafts, and a second adjusting shaft engageable with the first and third support shafts, and adjusts the three degrees of freedom of the projection unit on the basis of the combination of the engagements.
