Abstract
A bezel-less display panel, a display device, and a spliced display device are disclosed. The bezel-less display panel includes a first display area, a second display area around the first display area, and a third display area around the second display area. The third display area is not provided with a subpixel driving thin-film transistor. Some of driving thin-film transistors in the second display area are connected to light-emitting subpixels in the third display area through a plurality of metal lines.
