Patent ID: 8337025

Claim:
A projection type display device comprising: a light source; a liquid crystal panel having a first image display area and a second image display area formed in one body and optically modulating light flux from the light source by the first image display area and the second image display area based on a first video signal and a second video signal, both inputted from an outside, thereby to produce a first image and a second image; a projection optical system having an emitting part and projecting respective fluxes as projection light flux, which are obtained by optically modulating the light flux by the liquid crystal panel, from the emitting part; a first screen for displaying the first image since the projection light flux is irradiated to the first screen; a second screen arranged between the emitting part and the first screen in a direction perpendicular to the first screen for displaying the second image since the projection light flux is irradiated to the second screen; and a support frame arranged on an outside part of the first screen to have an optical transparency, and defining respective fluxes of the projection light flux irradiated to the first screen and the second screen as a first partial flux and a second partial flux, respectively, wherein the second screen is arranged in such a position that the first screen is not overlapped with a shadow of the second screen which is produced since the projection light flux emitted from the emitting part is irradiated to the second screen, wherein an extension area of the second partial flux transmitted through the second screen intersects with the support frame.
