Display panel and display device

The invention discloses a display panel and a display device. The display panel comprises a display area and a non-display area surrounding the display area. The display area comprises a plurality ofdata lines; the non-display area comprises a plurality of data source lines; the display panel further comprises a flexible circuit board. The flexible circuit board comprises a driving chip and a plurality of connecting lines; the data line extends along a first direction; a data signal output by the driving chip is transmitted to the data line through the connecting line and the data source line; one connecting wire and one data source wire which are electrically connected with each other form a connecting wire group; the maximum resistance Rmax and the minimum resistance Rmin in the resistors of the connecting line sets meet the requirement that the included angle theta between the long side of the driving chip and the first direction is larger than or equal to 0 degree and smaller than90 degrees.
