An image display device includes a rear cover to receive a display panel. The rear cover is provided with a deformation alleviating portion that deforms due to expansion of a surrounding portion caused by thermal stress. The deformation alleviating portion reinforces the rear cover and prevents thermal deformation of the rear cover, enabling realization of a slim image display device.
