• a plurality of light sources;
• and
• a light guiding plate guiding light emitted from the light sources,
• wherein the light sources are arranged corresponding to a side of the light guiding plate and the side includes a central portion, and
• the light sources are arranged at uniform intervals, and distances between the light sources and the display region are gradually reduced approaching the central portion.

A display device comprising:

• a display panel which displays images;
• a plurality of light sources mounted on an upper surface of a printed circuit board and providing light to the display panel;
• and
• a light guiding plate which guides light emitted from the light sources,
• wherein the light sources have a light emitting surface substantially perpendicular to the upper surface of the printed circuit board,
• the light emitting surface faces a side surface of the light guiding plate,
• the side surface of the light guiding plate includes a central portion,
• the light sources include first light sources as a first group arranged on the central portion of the light guiding plate, and second light sources as a second group adjacent to the first group, and
