Patent attributes
A display device includes a substrate having a first surface and a second surface opposite to the first surface. The display device also includes a first conductive layer disposed on the first surface and a second conductive layer disposed on the second surface. The first conductive layer and the second conductive layer are disposed on the opposite sides of the substrate. The display device further includes a connective portion at least partially disposed in the substrate and penetrating from the first surface to the second surface. The first conductive layer is electrically connected to the second conductive layer through the connective portion. The display device further includes a light-emitting element disposed on the first surface. The light-emitting element includes a first electrode and a second electrode. Along a direction perpendicular to the first surface, the first electrode and the second electrode are not overlapped with the connective portion.
