Display panel and display device

A display panel, comprising a base substrate, and the display panel further comprising:

• a light-transmitting region, a display region at least partially surrounding the light-transmitting region, and a peripheral region between the display region and the light-transmitting region;
• a plurality of pixel drive circuit units, the plurality of pixel drive circuit units being at least partially in the display region;
• n first signal lines, configured to supply a first signal to the plurality of pixel drive circuit units, wherein at least one of the first signal lines comprises a first main body portion in the display region, a first extending portion and a first bending portion in the peripheral region, the first extending portion is electrically connected with the first main body portion, and the first bending portion at least partially surrounds the light-transmitting region, and is farther away from the first main body portion than the first extending portion,
• wherein among the n first signal lines, a distance between first extending portions of two adjacent first signal lines is greater than a distance between first bending portions of the two adjacent first signal lines;
• a touch layer, comprising a first touch signal line in the display region and a first connecting portion in the peripheral region, the first connecting portion being electrically connected with the first touch signal line;
• m second signal lines, wherein the m second signal lines are configured to supply a second signal to the plurality of pixel drive circuit units, and the first connecting portion at least partially overlapps with an orthogonal projection of the m second signal lines on the base substrate;
• and
• a light emitting element, comprising a first electrode, a light emitting layer, and a second electrode, wherein the first electrode is on a side of the n first signal lines away from the base substrate, and is electrically connected with at least one pixel drive circuit unit, the second electrode is on a side of the first electrode away from the base substrate, and the light emitting layer is between the first electrode and the second electrode,
• wherein among the n first signal lines, a distance between first extending portions of two adjacent first signal lines is b1, among the n first signal lines, a distance between a first extending portion of at least one of the first signal lines and the second electrode in the direction perpendicular to the base substrate is H1;
• among the m second signal lines, a distance between two adjacent second signal lines in a region overlapping with the first connecting portion is b2, and among the m second signal lines, a distance between at least one of the m second signal lines and the second electrode in the direction perpendicular to the base substrate is H5,
• b1>b2, and H5>H1.
