A display panel includes: a transparent substrate with a display area including a light-emitting area and a non-light-emitting area; a light-emitting device on the transparent substrate, where the light-emitting device includes a first transparent electrode layer, a light-emitting functional layer and a second transparent electrode layer; the light-emitting functional layer includes light-emitting parts arranged in an array, and the light-emitting parts are in the corresponding light-emitting area; a driving structure between the transparent substrate and the light-emitting device, where the driving structure includes pixel circuits arranged in an array and a power supply line electrically connected to the pixel circuits to provide a power voltage, the pixel circuits are configured to drive the light-emitting parts to emit light; and orthographic projections of the pixel circuits and the power supply line on the transparent substrate are all located within an orthographic projection range of the non-light-emitting area on the transparent substrate.

Display panel and display apparatus

A display substrate includes a plurality of pixel units arranged to form a plurality of pixel columns extending along a first direction, the display substrate further includes a plurality of groups of power source signal lines and pixel driving circuits located on the substrate, each group of power source signal lines includes a plurality of secondary signal lines, the pixel driving circuits of the pixel units in each pixel column are connected to different secondary signal lines in a same group of power source signal lines, each secondary signal line extends along the first direction from a starting end of the power source signal lines, extension lengths of the secondary signal lines in the same group of power source signal lines are different, and resistance values per unit length of different secondary signal lines along the first direction decrease as total lengths of the secondary signal lines increase.
