PROBLEM TO BE SOLVED: To provide a projection-type video display device where a projection lens opening formed in a front face of a body case and an operation opening formed in a surface adjacent to the body case are protected against dust and impact to protect a projection lens portion against them. SOLUTION: The projection-type video display device displays video by modulating light from a light source based on a video signal and projecting the modulated light through the projection lens 2 exposed from the opening 3 in the front face 1a of the body case. An operation member (adjustment dial 4) for adjusting the zoom, focus, etc. of the projection lens 2 is exposed from the operation opening 5 formed in the surface (upper surface 1b) adjacent to the front face 1a of the body case. Also, a slide cover 7, etc. for opening and closing both the projection lens opening 3 and the operation opening 5 are provided in the body case 1a via a slide holder 9 so as to freely slide. A holding mechanism that holds the slide cover 7 between the slide cover 7 and slide holder 9 is formed. COPYRIGHT: (C)2008,JPO&INPIT
