    Abstract: Disclosed are a light emitting diode display device and a multi-screen display device using the same, which include a reduced or minimized bezel area. The light emitting diode display device includes a substrate including a first display area and a second display area outside of the first display area, a plurality of first unit pixels in the first display area, the plurality of first unit pixels each including a plurality of subpixels each including a micro light emitting device, and a plurality of second unit pixels in the second display area adjacent an edge of the substrate. A distance between the second unit pixel and an outer surface of the substrate is equal to or less than half of a reference pixel pitch at which the plurality of first unit pixels are arranged.
