## Abstract

A connecting component, a display panel, and a display device are provided. The connecting component includes a first plane and a second plane which are perpendicular to each other. The first plane is provided with a plurality of first terminals, the second plane is provided with a plurality of second terminals corresponding to the first terminals. Each of the first terminals is connected to a corresponding second terminal by a conducting wire. The connecting component may improve display effect of the display device formed by splicing the display panels, reducing risks of wiring breakage of a chip on flex (COF).
