FIG. 2 is a schematic perspective view of the rear cover included in the display device according to some exemplary embodiments of the present disclosure. Referring to FIG. 2, the rear cover 1 includes a rear cover board 15 and four side boards 11, 12, 13 and 14. The four side boards 11, 12, 13 and 14 respectively extend from the rear cover board 15 toward the back side of the display device 100, and the four side boards 11, 12, 13 and 14 are substantially perpendicular to the rear cover board 15, respectively. The four side panels are connected end to end to form a surrounding structure. The rear cover board 15 has a first concave portion 151 and a second concave portion 152. The first concave portion 151 is closer to the display side of the display device 100 than the second concave portion 152. That is, a depth of the first concave portion 151 is greater than a depth of the second concave portion 152.
