PROBLEM TO BE SOLVED: To provide an active matrix type liquid crystal projection device that is small, lightweight, clear and free of visual dependency. SOLUTION: The device is so structed that a dichroic mirror 43, 44 is provided which splits light outgoing from a single light source 40 to project to a different optical path, that a liquid crystal panel 21, 22, 23 is arranged on each optical path of the light projected through the dichroic mirror 43, 44, that the projected light of the three primary colors transmitted through each liquid crystal panel 21, 22, 23 is projectively displayed after being made coincident on the same optical axis by an optical path refracting means, and that a cooling means is provided which controls rise in temperature of the liquid crystal panel 21, 22, 23. |
