1. A display device comprising:
a display panel;
an optical assembly providing light to the display panel;
a light absorbing layer located on an optical path of light provided from the optical assembly to the display panel and absorbing light of a certain range of wavelengths;
an optical plate opposite the display panel with respect to the light absorbing layer; and
a first pad located at a front surface of the light absorbing layer adjacent to an edge of the light absorbing layer, and including a fluorescent layer,
wherein white light is incident on the display panel,
wherein the light absorbing layer comprises phosphor, and
wherein a color of light emitted by the phosphor and the fluorescent layer is complementary to a color of light emitted from the optical assembly;
wherein the display device further comprises:
a substrate extending along a lateral side of the optical plate; and
a guard positioned on the substrate and facing the lateral side of the optical plate,
wherein the optical assembly comprises a plurality of optical assemblies positioned on the substrate, facing the lateral side of the optical plate, and arranged along a longitudinal direction of the substrate,
wherein the guard comprises a plurality of slots which are spaced apart from each other in the longitudinal direction of the substrate, and in which the plurality of optical assemblies are positioned,
wherein a distance between a portion of the guard excluding the plurality of slots and the lateral side of the optical plate is smaller than a distance between the plurality of optical assemblies and the lateral side of the optical plate.
