The invention provides an OLED display panel and a touch panel. The touch panel comprises a linear polarizer, a 1 / 2 wave plate layer, a 1 / 4 wave plate layer and a touch electrode layer, wherein the 1 / 2 wave plate layer is formed on one side of the linear polarizer, the 1 / 4 wave plate layer is formed on one side, away from the linear polarizer, of the 1 / 2 wave plate layer, the touch electrode layer is formed on one side, away from the linear polarizer, of the 1 / 4 wave plate layer and comprises a plurality of touch electrodes, and the touch electrodes are meshed metal grids. The OLED display panel and the touch panel have the advantages that panel reflectivity is reduced, and panel touch precision is increased at the same time.
