AMOLED display panel and corresponding display device

A display device, comprising an active-matrix organic light-emitting diode (AMOLED) display panel, which comprises a plurality of first sub-pixels, a plurality of second sub-pixels and a plurality of third sub-pixels, wherein each of the plurality of first sub-pixels, the plurality of second sub-pixels, and the third sub-pixels comprises a light-emitting device and a pixel driving circuit, wherein the pixel driving circuit is disposed along a horizontal direction and along a vertical direction;

• wherein the pixel driving circuit comprises a driving transistor configured to determine a driving current of the pixel driving circuit;
• and wherein the driving transistor comprises a linear first active layer and a linear first gate disposed on the first active layer, the first active layer comprises a channel area overlapping with the first gate, and the channel area is straight-line-shaped;
• wherein the display panel further comprises a plurality of data lines and a plurality of gate lines connected to the plurality of first sub-pixels, the plurality of second sub-pixels and the plurality of third sub-pixels;
• wherein one of the plurality of first sub-pixels and one of the plurality of second sub-pixels are arranged along a direction in which the data lines extend, and one of the plurality of first sub-pixels and one of the plurality of second sub-pixels share one of the data lines;
• and wherein one of the plurality of first sub-pixels and one of the plurality of third sub-pixels are arranged along the direction in which the gate lines extend, and one of the plurality of first sub-pixels and one of the plurality of third sub-pixels share one of the gate lines;
• and
• wherein a size of the pixel driving circuit along the data line is less than a size of the pixel driving circuit along the gate line.
