Zusammenfassung:A chip-on-film structure and a liquid crystal panel having the chip-on-film structure. The structure comprises: a film (11), wherein a group of input end leads (111) and a group of output end leads (113) are arranged thereon, and a bonding portion (115) is formed at a tail end of each of the output end leads (113); and a driving chip (13) arranged on the film (10) and electrically connected to the input end leads (111) and the output end leads (113), wherein a connection point between the bonding portion (115) and a tail end of a corresponding output end lead (113) is defined as A, and a position, away from the tail end of the corresponding output end lead (113), of the bonding portion (115) is defined as B, a distance between A and B is L, and then, the area of the bonding portion (115) is greater than the area of the output end lead (113) corresponding thereto under the length L. By means of the chip (13) on film (11) structure, a bonding yield rate can be improved and the manufacturing cost can be reduced.
