A display device includes a display panel, a base, a circuit module, and a wall mount bracket. The sandbags of each course are positioned adjacent to each other side to side along their lengths, rather than their widths, so as to extend at about a right angle from the slope being supported. A driving sequence of the two pixels of the same pixel group is alternately changed in continuous image frames. A surface treatment procedure is performed on the first substrate with cathode structure thereon. Within each paddle group is at least one paddle where each paddle is formed of a frame having mesh disposed within the frame.
