Abstract:
1. An image display apparatus comprising: an illuminating optical system including a lamp light source which emits light and a reflecting mirror device having double reflecting mirror arrays formed in at least a portion of the reflecting mirror device for at least partly adjusting a divergent direction of the light emitted from the lamp light source; a spiral lens in which lens cells are formed spirally to obtain the effect of a rectilinear motion of a lens cell array due to a rotation of the spiral lens cell array so that a scrolling operation of the adjusted light: a light valve which controls the light emitted from the lamp light source and then reflected by the reflecting mirror device on a pixel-by-pixel basis according to an input image signal and forms a color image; and a colored light separator which separates the scrolling light according to wavelength, wherein the colored light separator includes three or more dichroic filters.
