The first digital micromirror device (DMD) modulates and reflects the first colored light, while the second DMD modulates and reflects the second and third colored lights guided by the first light guiding device. Subsequently, the second light guiding device guides the colored lights reflected from the first DMD and the second DMD to the projection lens.
