A display panel according to an embodiment is provided and includes a top substrate having an outer surface; a display layer covered by the top substrate; a patterned light shielding layer disposed on the outer surface of the top substrate and located within the first region; and a patterned oxide layer disposed on the outer surface of the top substrate. The outer surface comprises a first region and a second region beside the first region. An edge of the patterned light shielding layer at least partially overlaps a boundary between the first region and the second region. The patterned oxide layer is located within one of the first region and the second region while exposes the other of the first region and the second region.
