A projector for projecting images onto a screening member, comprising: a light source adapted to emit white light; a filter unit which has red, green and blue primary color filters and yellow, cyan, and magenta secondary color filters for dividing the white light from said light source into a plurality of primary and secondary color lights, respectively, the primary and secondary color filters being arranged in the order of red, yellow, green, cyan, blue and magenta; a spatial light modulator which is driven to project the color lights divided by said filter unit to said screening member to project said images; and a display driver, to which a plurality of primary color signals for generating said images to be projected onto said screening member are supplied, which is adapted to generate a white color signal and secondary color signals based on the supplied primary color signals, and is adapted to drive said spatial light modulator by supplying said primary color signals to said spatial light modulator so that primary colors of the supplied primary color signals correspond to primary color lights from said filter unit and by supplying the generated secondary color signals to said spatial light modulator so that secondary colors of the generated secondary color signals correspond to secondary color lights from said filter unit, wherein said display driver is adapted to execute one of a first display control option, a second display control option, a third display control option and a fourth display control option, during terms when the light divided by said filter unit is a color mixture of a primary and a secondary color; wherein, in said first display control option, said generated white color signal is supplied to said spatial light modulator; wherein, in said third display control option, the generated secondary color signal corresponding to the secondary color of said color mixture is supplied to said spatial light modulator; wherein, in said second display control option, the spatial light modulator is supplied with the supplied primary color signal corresponding to the primary color of said color mixture when the mixture rate of the primary color is higher than that of the secondary color, and supplied with the generated secondary color signal corresponding to the secondary color of said color mixture when the mixture rate of the secondary color is higher than that of the primary color; and wherein, in said fourth display control option, the supplied primary color signal corresponding to the primary color of said color mixture is supplied to said spatial light modulator. a light source adapted to emit white light;
