The present invention relates to a mobile terminal comprising a lighting device. The lighting device according to one embodiment of the present invention comprises multiple light-emitting elements and a diffractive optical element (DOE) for diffracting a part of the light which has been output from each of the multiple light-emitting elements, wherein the light, which has been output from the multiple light-emitting elements and has passed through the diffractive optical element, comprises multiple first kinds of light not diffracted by the diffractive optical element and multiple second kinds of light diffracted by the diffractive optical element, and the diffractive optical element diffracts the part of the light output from the multiple light-emitting elements such that at least some of the multiple second kinds of light is radiated into an area formed by connecting the multiple first kinds of light.
