Bendable display panel and display device

A display device, comprising:

• a display panel, wherein the display panel comprises:
• an array substrate having a display area and a non-display area surrounding the display area, wherein the display area comprises:
• a first display area being non-bendable;
• a second display area being bendable;
• a plurality of first pixel diving circuits, each including a plurality of first driving transistors, arranged in the first display area;
• and
• a plurality of second pixel diving circuits, each including a plurality of second driving transistors, arranged in the second display area;
• wherein a first width-length ratio of each of the plurality of first driving transistors is greater than a second width-length ratio of each of the plurality of second driving transistors;
• wherein a plurality of first organic light emitting diodes each corresponding to a respective first pixel driving circuit of the plurality of first pixel driving circuits is arranged in the first display area, wherein each of the plurality of first organic light emitting diodes comprises an anode and a cathode, wherein the anode is coupled to the plurality of first driving transistors in a respective first pixel driving circuit;
• wherein a plurality of second organic light emitting diodes each corresponding to a respective second pixel driving circuit of the plurality of second pixel driving circuits is arranged in the second display area, wherein each of the plurality of second organic light emitting diodes comprises an anode and a cathode, wherein the anode of the second organic light emitting diode is coupled to the plurality of second driving transistors in a respective second pixel driving circuit;
• wherein a difference between the first width-length ratio and the second width-length ratio is j, and a ratio of j to the first width-length ratio is k, and wherein k is smaller than 70%.
