<P>PROBLEM TO BE SOLVED: To provide an image display device which allows cooling such that an optical element which is an object element of cooling is set to a desired temperature, and allows efficient cooling and reduction of display unevenness. <P>SOLUTION: The image display device includes a light source that emits an illumination light; a liquid crystal display panel 19, that constitutes an optical modulation element modulating the illumination light emitted from the light source, according to an image signal; a display information processing section 42, that performs light control processing for adjusting the quantity of the illuminating light made incident on the optical modulation element, and extension processing of the image signal, corresponding to the light control processing by analyzing the image signal; and a cooling mechanism 31, that supplies cooling air to the optical element which is the element of object of cooling. The speed of the cooling air to be supplied to the optical element is controlled, according to the quantity of the illuminating light, adjusted by the light control processing in the display information processing section 42. <P>COPYRIGHT: (C)2011,JPO&INPIT |
