1. A display panel, comprising a display portion and a gate electrode driver circuit located on a side of the display portion, wherein the gate electrode driver circuit comprises a quantity N of driver units that are cascaded, the quantity N of the driver units are arranged along a first direction, and each of the driver units comprises a signal generation module, a first output module, and a second output module disposed along a second direction;
wherein the first output module is disposed on a side of the signal generation module near the display portion, and the first output module is configured to output a first gate electrode driving signal;
wherein the second output module is disposed on a side of the signal generation module away from the display portion, the second output module is configured to output a second gate electrode driving signal, and the first gate electrode driving signal is different from the second gate electrode driving signal;
wherein the first output module comprises a first buffer unit and a second buffer unit, the first buffer unit and the second buffer unit are stacked along a third direction, the third direction is perpendicular to a plane in which the first direction and the second direction are located, the second direction is parallel to scan lines of the display panel, an included angle between the first direction and the second direction is greater than 0° and is less than or equal to 90°, and the N is a positive integer;
wherein the first buffer unit comprises a first active portion, the second buffer unit comprises a second active portion, the first active portion is a metal oxide semiconductor, the second active portion is a silicon-containing semiconductor; and
wherein the first buffer unit is disposed near a light exiting side of the display panel, and the second buffer unit is disposed away from the light exiting side of the display panel.
