<p>In order to improve the brightness of the images displayed, disclosed is an image display device which is provided with a plurality of first-group filters (21 to 23) that allow the passage of a plurality of first-group light beams for representing a first color space, respectively, and a plurality of second-group filters (24 to 26) that allow the passage of a plurality of second-group light beams for representing a second color space wider than the first color space, respectively, and which includes a color wheel for emitting the light beams that have passed through the first and second-group filters (21 to 26) by means of time division, a detection means for detecting whether or not an image indicated by an image signal is located in the first color space, and a control means for causing the light beams that have passed the first and second-group filters (21 to 26) to be incident on a light modulation element if the detection means has detected that the image indicated by the image signal is located in the first color space, and causing the light beams that have passed the second-group filters (24 to 26) to be incident on the light modulation element if the detection means has detected that the image indicated by the image signal is not located in the first color space.</p> |
