A field sequential lighting device for emitting light corresponding to a plurality of colors using a field sequential method includes: a light source; and a light converting section for intensifying the emitted light by sequentially converting the light, emitted from the light source, corresponding to the plurality of colors. By doing this, it is possible to provide a field sequential lighting device using the light emitted from the light source efficiently and having desirable color reproducibility, and an image projecting device having it.
