Abstract
Device () for projecting an image into a display area (), with an imager () generating the picture, a first projection device () for generating a real intermediate image (R), a screen () onto which the first projection device () projects the intermediate image (R) and to a second projection device () projecting the intermediate image (R) into the display area (). In order to project the image with the least possible loss of brightness, the invention provides that main beam directions (H, H', H″) of the screen () point into an entrance pupil () of the second projection device ().
