1. A projection display system, comprising:
- a screen;
an illumination projecting system to form an image using light radiated by a light source, to magnify the image, and to project the image along a rear side of the screen; and
a reflection unit having an array of unit mirrors to reflect the image received from the illumination projecting system to the screen, each of the unit mirrors having a first sloped reflection surface and a second reflection surface adjacent to the first reflection surface having a predetermined angle therebetween.
