An image display device has a main display body provided with a thin display unit, a low-frequency loudspeaker (woofer) and two middle and high frequency loudspeakers (tweeters) and a stand supporting the main display body. The stand has a base being just opposite at its top surface to a duct outlet of the woofer, thereby sound emitted from the duct can be constantly absorbed by and reflected from the base. A housing containing the first loudspeaker and a pair of the second loudspeakers has a plurality of through holes formed in a first area corresponding to an aperture of each loudspeaker and a plurality of blind holes formed in a second area surrounding the first area, wherein the second area for the first loudspeaker is different in peripheral shape and/or size from the second area for each of the second pair of loudspeakers.
