Pixel driving circuit and display panel

The invention provides a pixel driving circuit and a display panel. The pixel driving circuit comprises a first light-emitting unit, a first driving unit, and a first capacitor unit connected in parallel on a path between the first light-emitting unit and the first driving unit; the first capacitor unit is used for consuming leakage current of the first driving unit. Specifically, according to the pixel driving circuit provided by the invention, the first capacitor unit is connected in parallel to the path between the first light-emitting unit and the first driving unit, and the first capacitor unit can consume the leakage current of the first driving unit when the display panel is electrified to display a black picture, so that the problem that the black is relatively bright when the display panel is electrified to display the black picture is solved. 本申请提供的像素驱动电路及显示面板，像素驱动电路包括第一发光单元、第一驱动单元、以及在第一发光单元与第一驱动单元之间的通路上并联的第一电容单元；其中，第一电容单元用于消耗第一驱动单元的漏流。具体的，本申请提供的像素驱动电路，通过在第一发光单元与第一驱动单元之间的通路上并联第一电容单元，在显示面板上电显示黑画面时，第一
