ARRAY TYPE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To efficiently discharge the hot air in the sections of drive circuits without the increase of a cost and the generation of noise when a plurality of display units having display devices and the drive circuits are arrayed in longitudinal and transversely directions. SOLUTION: The drive circuits 9 of the respective display units 1 are covered by covers 6 having an opening in a longitudinal direction, by which a piece of a so-called duct is formed by the covers 6 of the display units 1 of the same longitudinal array. The drive circuits 9 exist in this duct. The covers 6 of the plural longitudinal arrays display units 1 are connected to the common duct 13 and this duct 13 is provided with a fan 16 for passing air.
