PURPOSE: A display device is provided to improve light efficiency by injecting a host having different wavelength conversion particles into the groove of a light guide plate. CONSTITUTION: A light guide plate(200) is arranged under a display panel. A light source(300) is arranged in a first surface(208) of the light guide plate. A first and a second wavelength conversion part(701,702) are arranged in the inner part of a first groove(203) and a second groove(204) which are formed on a second surface(207) or a third surface(209) of the light guide plate. The hosts(440) of the first and the second wavelength conversion part are directly contacted with the inner part of the groove. The wavelength conversion particles(431,432) of the first and the second wavelength conversion part are dispersed into the hosts.
