Abstract: The present invention relates to a display apparatus. According to an embodiment of the present invention, the display apparatus comprises a plurality of displays adjacently arranged, wherein each of the plurality of displays comprises a panel, a bezel surrounding the panel, and a plurality of light sources disposed on a circuit board and configured to output light to the panel, wherein the plurality of light sources comprises a first light source disposed at a first area of the circuit board the bezel and a second light source disposed at a second area of the circuit board, wherein the first area is adjacent to the bezel, and wherein a first current is provided to the first light source and a second current is provided to the second light source and the second current is smaller than the first current. Thereby, decrease in brightness in areas near the bezel can be compensated for, and uniform brightness can be implemented throughout the displays.
