The invention discloses a display panel and a manufacturing method thereof, and the display panel comprises a first substrate and a second substrate disposing correspondingly to each other, a pixel array disposed between the first substrate and the second substrate and an electrode disposed on a first substrate surface near the second substrate, and a through hole is disposed correspondingly to the second substrate and the electrode to expose part of the electrode by passing through the through hole. By applying the above-described method, the invention can achieve embedding functional components within the display panel, furthermore save a disposing space, increase a screen portion of display panel, and then improve using experiences of users.
