Tiling display device

A tiling display device, comprising:

• a plurality of display devices, each including:
• a display panel including an active area and a non-active area surrounding the active area, the display panel including a front surface, a side surface, and a rear surface;
• a plurality of pixels in the active area;
• a first pad electrode on the front surface of the display panel in the non-active area;
• a second pad electrode on the rear surface of the display panel in the non-active area;
• a side line extending along a part of the front surface, an entire side surface, and a part of the rear surface of the display panel, the side line electrically connecting the first pad electrode and the second pad electrode;
• and
• a side insulating layer covering the side line and disposed on the front surface, the side surface, and the rear surface of the display panel,
• wherein, in a first display device and a second display device adjacent to each other among the plurality of display devices, a distance between an outermost pixel of the first display device and an outermost pixel of the second display device is equal to a distance between adjacent pixels within each of the first display device and the second display device, and
• wherein the outermost pixel of the first display device and the outermost pixel of the second display device are adjacent to each other.
