The invention provides a touch panel. The touch panel comprises a substrate, a low-temperature polycrystalline silicon layer, a first insulating layer, a grid, a second insulating layer, a source, a drain, a flat layer, a filling part, a third insulating layer and a pixel electrode, wherein the low-temperature polycrystalline silicon layer, the first insulating layer, the grid and the second insulating layer are sequentially stacked on the surface of the substrate; the source and the drain are disposed on the second insulating layer at interval, and the source and the drain are respectively connected with the low-temperature polycrystalline silicon layer by through holes; the flat layer is stacked on the source, the drain and the second insulating layer, and the flat layer is provided with a first through hole which corresponds to the drain; the first through hole is filled with the filling part which is electrically connected with the drain; the third insulating layer is stacked on the flat layer and provided with a second through hole corresponding to the filling part; the pixel electrode is disposed on the third insulating layer and electrically connected with the filling part through the second through hole. The pixel electrode of the touch panel is less prone to disconnection and falling.
