The invention provides a display panel and a 
display device. The display panel comprises a pixel 
driving circuit, a driving 
transistor and a first connecting portion. The pixel 
driving circuit comprises scanning lines, 
data lines and a power line, the scanning lines are used for transmitting scanning signals, the 
data lines are used for transmitting data signals, and the power line is used for transmitting 
constant voltage signals; the scanning lines are positioned on a first 
metal layer, the power line is positioned on a second 
metal layer, the 
data lines are positioned on a third 
metal layer, and the second metal layer is positioned between the first metal layer and the third metal layer; a gate 
electrode of the driving 
transistor is positioned on the first metal layer and is connected with the first connecting portion; the power line is positioned between the data lines and the first connecting portion. The display panel and the 
display device have the advantages that 
coupling parasitic capacitance of the data lines and first 
coupling portion can be diminished, offset of driving currents of the driving 
transistor can be diminished, and interference on the 
luminescence intensityof organic 
luminescence components can be diminished.
