Abstract: A display apparatus is provided. The display apparatus includes a first light source unit comprising a first light source that emits light having a first spectral band and a photo-converter that converts the light having the first spectral band to a first color light. A spectral band of the first color light is different from the first spectral band of the light emitted from the first light source. The display apparatus also includes a second light source unit comprising a second light source that emits light having a second spectral band. The light having the second spectral band corresponds to a second color light, and has a same color as the light having the first spectral band.
