Abstract
Abstract Inserted from the rear in an inner housing (2) of a liquid crystal display is a cooling element (9), which has vertical cooling ribs and carries a fluorescent tube (12) on a front plate (10) facing the liquid crystal cell (3). The ends (13) of the fluorescent tube (12) project through the front plate (10) into the cooling element (9). Air is conducted through the cooling element (9) by means of a fan (17), so that the heat generated by the fluorescent tube (12) can be effectively dissipated. <IMAGE>
