Abstract
PURPOSE:To obtain the continuous display of large screen with high definition by constituting a large liquid crystal panel by combining plural small liquid crystal panels, and projecting an image on the liquid crystal panel on a transmission type screen by enlarging by a projecting lens. CONSTITUTION:Image light is generated by transmitting the liquid crystal panel 5 on which light from a halogen lamp 1 forms the image, and the image light is projected on the transmission type screen 7 by transmitting the projecting lens 6, and the image on the liquid crystal panel 5 is expanded and image- formed on the back plane 7a of the screen 7. A person visualizes the image displayed on the surface 7b of the screen 7 on the opposite side of the liquid crystal panel 5. At this time, the image with width A on each picture plane 16 of the liquid crystal panels 5a, 5b... is expanded to the image with width B, respectively, by the projecting lenses 6a, 6b..., and is projected on the screen 7. In such a case, the images of adjacent liquid crystal panels 5a, 5b... are projected on the screen 7 as the image continuing with each other. Therefore, no black part of unrequired grid shape is generated on the image on the screen 7, and satisfactory display definition can be obtained.
