<p>A projection pad has a transmission type liquid crystal panel (4) for providing a display for projection onto a projection surface, and an axial flow blower (6) for generating an air flow for cooling the panel. A space forming an air passageway is provided between the panel and an outer casing (1, 5) of the pad by means of ribs (7). External air drawn in by the axial flow blower is directed by the blower into the air passageway so as to flow over the panel for cooling purposes.</p> |
