ABSTRACT:
A liquid crystal display apparatus is constituted by: a housing; a liquid crystal panel comprising a liquid crystal disposed between a pair of substrates each provided with electrodes, the liquid crystal panel being affixed to the housing; and a backlight for illuminating the liquid crystal panel, detachably affixed to the housing. A light-transmissive plate, such as a diffusion plate, allowing transmission of light from the backlight is further disposed between the liquid crystal panel and the backlight so as to define an almost closed first space in cooperation with the liquid crystal panel, whereby the first space retaina its almost closed state even when the backlight is detached from the housing.
