Claim:
1. A display panel including a first substrate and a second substrate which are arranged opposite to each other, and an outer surface of the second substrate includes a display region and a border region surrounding the display region, wherein, the display panel further includes a plurality of light guides provided on the outer surface of the second substrate, the light guides include first light guides, which are provided at edges of the display region so as to guide light emitted from the edges of the display region towards an upside of at least a part of the border region; wherein, each of the first light guides is a columnar element and includes a mounting surface, a refraction surface, and a connection surface connecting the mounting surface and the refraction surface, the mounting surface is attached to the outer surface of the second substrate, a distance between each of points on the refraction surface and the connection surface gradually increases from top to bottom, and light emitted from the edges of the display region travels from the refraction surfaces towards an upside of the border region after being refracted by the first light guides; wherein, the border region includes functional sections and connection sections, the functional sections are respectively located at two opposite sides of the border region, the connection sections are respectively located at remaining two sides of the border region and are connected between the functional sections located at the two opposite sides, each of the first light guides which extend along a length direction of each of the connection sections is arranged adjacent to each of the connection sections located at the remaining two sides; or each of the first light guides which extend along a length direction of each of the functional sections is arranged adjacent to each of the functional sections located at the two opposite sides; and wherein, the light guides further include second light guides provided on the outer surface of the second substrate, the second light guides are located between the first light guides arranged opposite to each other, bottom surfaces of the first light guides and the second light guides cover the display region, and a magnification of each of the second light guides is the same as that of each of the first light guides, wherein the display panel further includes a solar cell, which is provided on the outer surface of the second substrate and at an inner side of each of the second light guides.
