ABSTRACT:
A projection-type display device of the present invention includes a projection unit for projecting an image to be displayed on a screen and an angle-of-projection correcting mechanism supporting the projection unit. The angle-of-projection correcting mechanism is located at a side surface of the projection unit, instead of on a bottom surface thereof, to correct the projection angle of the image projected from the projection unit onto the screen, while reducing the size of the projection-type display device.
