PROBLEM TO BE SOLVED: To provide a projection type image display device capable of realizing a bright, high-resolution and uniform display and contributing to downsizing and cost reduction. SOLUTION: A light source 1, an image display panel 8 including multiple pixel regions, each of which can modulate light, light control means 4 to 6 for focusing light from the light source 1 onto associated pixel areas according to their wavelength ranges, and optical systems 9 and 11 that form an image on a projection plane 13 by the light that has been modulated by the panel 8 are provided. A circuit for generating data representing multiple image subframes from data representing each image frame as a component of the image and getting the subframes displayed by the panel time-sequentially, and an image shifter 11 for shifting a selected one of the subframes on the projection plane are further provided. The same area on the projection plane 13 is sequentially irradiated with light rays that have been modulated by different pixel areas of the panel 8 and that fall within respectively different wavelength ranges.
