Claim 0:
1. A display panel, comprising a plurality of subpixels, wherein:
a subpixel of the plurality of subpixels comprises a pixel circuit and a light emitting element that are electrically connected, the pixel circuit comprises a first transistor, a first electrode of the first transistor is connected to a first reference voltage signal terminal, and a second electrode of the first transistor is electrically connected to an anode of the light emitting element;
in a light emitting retention stage of the subpixel of the plurality of subpixels, the first reference voltage signal terminal is connected to a negative potential signal or a ground potential signal;
the plurality of subpixels comprises at least a first subpixel and a second subpixel, and a color of the first subpixel is different from a color of the second subpixel; and
a width-to-length ratio of a channel region of the first transistor in the first subpixel is N1, a width-to-length ratio of a channel region of the first transistor in the second subpixel is N2, and N1>N2.
