PROBLEM TO BE SOLVED: To provide a backlight for uniformly lighting a display panel by a structure which does not use a light guide plate.SOLUTION: This backlight assembly 200 includes: an optical guide member extending to one direction and having a light incident face and a light emitting face; a light source 210 arranged so as to oppose the light incident face of the optical guide member and providing light to the optical guide member via the light incident face; and a reflection member 230 which reflects light in order to emit light from the light emitting face of the optical guide member. The reflection member includes a groove in which the optical guide member is arranged, a first reflection part 231 arranged at the lower part of the optical guide member and reflecting light which is refracted by the optical guide member to the upper direction, and a second reflection part 232 arranged at the upper part of the optical guide member and reflecting the light which is refracted by the optical guide member to the lower direction. By this, even the edge-type backlight assembly structure which does not use the light guide plate can transmits light which is uniform in luminance to the display panel, and a manufacturing cost can be reduced by reducing the number of light-emitting diodes. |
