たプロジエクシヨンパツド。[Claims for Utility Model Registration] (1) A device with a built-in axial fan and a transmissive liquid crystal panel placed between a light source and a projection surface, so that the content displayed on the liquid crystal panel is projected onto the projection surface. In the projection pad using the constructed liquid crystal panel, the space in the thickness direction sandwiched between the transmissive liquid crystal panel and the exterior case is formed into a tunnel-like space as an air passage by ribs erected in the thickness direction. By creating a space, the outside air is fluid-dynamically connected to the outside air through the ventilation hole opened in the exterior case, the axial flow fan, the tunnel-shaped space as a passage for the air, and the outside air through the other ventilation hole. A projector pad that uses a liquid crystal panel. (2) The projection pad using a liquid crystal panel according to claim 1, wherein the axial fan is configured to suck outside air and blow the air onto the liquid crystal panel.
