A display apparatus includes a housing having a pillar shape, a plurality of monitors, and a driving unit received in the housing and providing driving signals to the plurality of monitors. Each of the plurality of monitors displays an image through its front surface and back surface and includes side surfaces connecting the front surface and the back surface. One side surface of the side surfaces of each of the plurality of monitors is coupled to the housing. A thickness of each of the plurality of monitors decreases as a distance from the housing increases.
