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.

Abstract: A display device includes a light guide plate including an inorganic material. A lower chassis includes a bottom portion, which overlaps with the light guide plate, a first sidewall, which faces a first side surface of the light guide plate, and a second sidewall, which extends from the bottom portion and faces a second side surface of the light guide plate. A light source is disposed on the first sidewall and faces the first side surface. A display panel structure is disposed on the light guide plate and is coupled to the lower chassis via a first panel coupling member. The display panel structure includes a display panel. A first buffer member is disposed between the second sidewall and the second side surface. A first reflective member is disposed between the first buffer member and the second side surface.
