Abstract: <P>PROBLEM TO BE SOLVED: To provide a projector which has a high performance despite being compact and inexpensive.  <P>SOLUTION: Addressing light beams ABa, ABb and ABc are made incident on the back face of a light addressing liquid crystal 20 with a clearance of one pixel in the Y-direction of subscanning. The incident points of the addressing light beams ABa, ABb and ABc move in the X-direction of main scanning at a constant speed. Illumination light beams CLa, CLb and CLc are also made incident on a readout face 20b with a clearance of one pixel in the Y-direction of subscanning direction. The incident points of the respective illumination light beams CLa, CLb and CLc move at a constant speed in the X-direction. In this case, the respective illumination light beams are made incident on the positions which are dislocated with respect to the addressing light beams by several pixels in the X-direction. As a result, a readout with the illumination light beams is performed with a time delay of scanning time equivalent to several pixels after the writing-in with the addressing light beams.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
