Abstract: A tiling display device includes a plurality of display modules arranged on one plane. The display module includes a substrate, a signal line, an open hole, a filling layer, and a circuit board. The substrate has a display area in which subpixels are defined. The signal line is positioned on the top surface of the substrate within the display area to deliver a predetermined signal to the subpixels. The open hole is provided to penetrate the substrate within the display area. The filling layer fills the open hole. The circuit board is positioned on the back surface of the substrate and electrically connected to the signal line through the filling layer.
