Claim 3:
4. The display panel according to claim 2, further comprising:
a second scanning driving circuit,
wherein the second scanning driving circuit comprises second scanning driving units that are cascaded, wherein each of the second scanning driving units is electrically connected to the data writing control terminal of one of the pixel driving circuits;
each of the second scanning driving units comprises a first output transistor configured to electrically connect an output terminal of the second scanning driving unit and a clock terminal; and
a width to length ratio of a channel of the first output transistor of one of the second scanning driving units that is electrically connected to the first pixel driving circuit is W11/L11, and a width to length ratio of a channel of the first output transistor of one of the second scanning driving units that is electrically connected to the second pixel driving circuit is W21/L21, wherein W11/L11<W21/L21.
