Tiling display device

A tiling display device, comprising:

• a plurality of display devices;
• and
• a main circuit board driving the plurality of display devices,
• wherein each of the plurality of display devices includes,
• a display panel that displays an image;
• one or more flexible films bonded to a rear surface of the display panel;
• and
• a printed circuit board electrically connected to the one or more flexible films,
• wherein a plurality of printed circuit boards of the plurality of display devices are cascaded to each other,
• wherein the plurality of printed circuit boards have a same shape,
• wherein a first printed line to an n-th printed line are disposed on each of the plurality of printed circuit boards, where n is a natural number of 2 or more, and
• wherein the first printed line to an m-th printed line of a first printed circuit board are respectively connected to a (m+1)th printed line to a 2m-th printed line of a second printed circuit board adjacent to the first printed circuit board, where m is a natural number less than n or equal to n, and
• wherein the display panel includes a micro-light emitting diode (LED), the micro-LED including an n-type semiconductor layer, a p-type semiconductor layer, and a light emitting layer.
