1. A display device comprising a display panel and a plurality of chip on films arranged along a first edge of the display panel, the plurality of chip on films being divided into a plurality of groups of chip on films, and each group of chip on films comprising at least two chip on films, and being bonded to one or more circuit boards of the display panel at a fan-out region through a same anisotropic conductive film; each group of chip on films corresponds to one circuit board;
wherein the number of groups of the chip on films is an even number, the number of chip on films in each group of chip on films is equal, and the plurality of groups of chip on films are symmetrically distributed about a perpendicular bisector of the first edge;
wherein a diagonal length of a display area of the display panel is not greater than 60 inches, the number of pixels of the display panel in a first direction is greater than the number of pixels in a second direction, the first direction and the second direction are perpendicular to each other, and the number of pixels in the first direction is not less than 7600;
wherein a distance between the circuit boards is not less than 3.8 mm and not greater than 4.5 mm.
