PURPOSE: A projector is provided to minimize the size of the projector by simplifying a light diffusing unit for each color light source. CONSTITUTION: Each color light source unit has at least more than one LED(Light Emitting Diode) as a light source. A display device converts video signal into a projection picture. The display device(400) reflects the provided composite light in the light tunnel and changes the light into the incident light. The incident light from the display device is projected to a screen through projection lens(500).
