This application discloses a display panel and a repairing method thereof. The display panel includes a color filter substrate, the color filter substrate including a substrate, color filter layer, an Indium Tin Oxide layer, and conducting components. The color filter layer is disposed on the substrate. The Indium Tin Oxide layer is disposed on the color filter layer. Repairing point is disposed on a same position of the color filter layer and the Indium Tin Oxide layer. The conducting components are filled in the repairing point to be electrically connected to the Indium Tin Oxide layer on both sides of the repairing point, to form complete the Indium Tin Oxide layer. The conducting components have a same color as color of the color filter layer on both sides of the repairing point.
