Abstract:
1. A projection type display comprising: a first light-source unit; a second light-source unit disposed at an approximately perpendicularly intersecting angle relative to an optical axis of said first light-source unit; a reflective polarizing plate disposed in an intersecting position of light beams emitted from both said first and second light-source units at an angle of approximately 45 degrees relative to optical axes of said first and second light-source units; a reflecting mirror disposed approximately parallel with said reflective polarizing plate to reflect light beams outputted from the reflective polarizing plate; first and second lens array plates adapted to make approximately uniform the light beams reflected from said reflective polarizing plate and said reflecting mirror, said first and second lens array plates each including a plurality of lens cells; image display elements adapted to modulate the light beams outputted from said first and second lens array plates into optical images in accordance with video signals; and a projection lens adapted to project as a color image the light beams outputted from said image display units; wherein a secondary light-source image of said first light-source unit and a secondary light-source image of said second light-source unit are formed at respective different positions on one and same lens cell of said second lens array plate.
