The illumination optical system (20) condenses an emitted light from the light emitting member (101) drove by the driving circuit (103) onto the portion to be illuminated. The light emitting members (101) are mounted on the rotatable substrate (102,114). The motor (106) operates the rotatable substrate (102,114) in a predetermined period to move the light emitting member (101). So as to select the light to illuminate the portion to be illuminated from the lights of the plurality of light emitting members (101), the LEDTG (105) controls the driving circuit (103) and the motor control circuit (107) controls the motor (106).The apparatus also includes: the illumination optical system (20) for efficiently illuminating the image display element (30) with the light from the LED (101); the image display element (30) represented by LCD for displaying the image; and the projection optical system (40) for enlarging/projecting the image from the image display element (30) on the screen (S). |
