<P>PROBLEM TO BE SOLVED: To provide a projector which has excellent moving picture display characteristics and uniform in-plane display characteristics, and has the manufacture cost and the power consumption of which are prevented from getting higher. <P>SOLUTION: The projector includes: liquid crystal devices 400R, 400G and 400B; a projection optical system 600; an illuminating device 100 for emitting illumination luminous flux having a sectional shape compressed in a y-axis direction; and a rotating prism 770 rotating at fixed speed and scanning the image forming area of the liquid crystal device with the illumination luminous flux from the illuminating device in the y-axis direction. The illuminating device 100 has a light control device 700 arranged between a 1st lens array 120 and a 2nd lens array 130 and adjusts the light quantity of the illumination luminous flux in accordance with the position of the illumination luminous flux on the image forming area so as to reduce the difference of illuminance caused by changing the scanning speed of the illumination luminous flux on the image forming area S in the liquid crystal device. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
