Display panel and display device

A display device comprising a display panel, wherein the display panel comprises multiple pixel driving circuits arranged in an array along a first direction and a second direction, the multiple pixel driving circuits comprise first pixel driving circuits and second pixel driving circuits distributed at intervals along the second direction, the second direction intersects with the first direction, and the display panel further comprises:

• a base substrate;
• a first metal layer located on a side of the base substrate, wherein the first metal layer comprises multiple fan-out transposition lines, and orthographic projections on the base substrate of the multiple fan-out transposition lines extend along the first direction;
• and
• a second metal layer located on a side of the first metal layer away from the base substrate, wherein the second metal layer comprises multiple data signal lines and multiple data fan-out lines, orthographic projections on the base substrate of the multiple data signal lines extend along the second direction and are distributed at intervals along the first direction, and orthographic projections on the base substrate of the multiple data fan-out lines extend along the second direction and are distributed at intervals along the first direction;
• wherein the multiple data signal lines comprise multiple first data signal lines and multiple second data signal lines alternately distributed along the first direction, a pixel column corresponds to one of the first data signal lines and one of the second data signal lines, and the first data signal line and the second data signal line are arranged on both sides of the pixel column that the first data signal line and the second data signal line correspond to, and wherein the first data signal line is connected to the first pixel driving circuits, and the second data signal line is connected to the second pixel driving circuits;
• and
• wherein at least some of the data signal lines far away from a middle area of the display panel are connected to the fan-out transposition lines, and the fan-out transposition lines are further connected to the data fan-out lines close to the middle area of the display panel.
