Abstract: A backlight unit is described. The unit includes a light emitting array having a plurality of light sources configured to emit light, and a printed circuit board on which the light sources are arranged; a light guide film configured to guide light emitted from the light sources in one direction; a color conversion layer configured to convert light that has passed through the light guide film into light of a specific color; and an optical member disposed on the color conversion layer. The light sources include first light sources arranged on a first row of the printed circuit board, and second light sources arranged on a second row of the printed circuit board. The first light sources are spaced apart from each other by a predetermined distance, and the second light sources are spaced apart from each other by the predetermined distance.
