In addition, in the fourth frame area, due to the effect of the fourth auxiliary line, voltage transmission on the anode power supply connecting line is shared, so that the anode power supply line can be arranged narrower in the fourth frame area, the space occupation of the anode power supply line in the fourth frame area is reduced, and the realization of a narrow frame is facilitated.
Alternatively, as shown in fig. 2, the first auxiliary connection line 41, the second auxiliary connection line 42, the third auxiliary connection line 43, and the fourth auxiliary connection line 44 are located at the anode layer 22. Namely, when the anode layer 22 is manufactured, the auxiliary connecting lines are formed through the same composition process, so that the auxiliary connecting lines do not need to be manufactured independently, the process difficulty is reduced, and the auxiliary connecting lines and the anode power line 3 can be ensured to be positioned at different layers, thereby ensuring the sharing function in the anode signal transmission process and realizing the reduction of the voltage drop on the anode signal line.

Alternatively, as shown in fig. 1 and fig. 5, fig. 5 is another schematic structural diagram of another organic light emitting display panel in the embodiment of the invention, the auxiliary connecting lines 4 further include a plurality of display area auxiliary connecting lines 40 located in the display area 11, the plurality of display area auxiliary connecting lines 40 are arranged along the second direction h2, and two ends of each display area auxiliary connecting line 40 are electrically connected to the first auxiliary connecting line 41 and the second auxiliary connecting line 42, respectively.

It should be noted that fig. 5 only illustrates the structures of the auxiliary connection line 4 and the anode E1, and other structures may be the same as those illustrated in fig. 1, and a difference between fig. 5 and fig. 1 is that the auxiliary connection line 40 in the display area in fig. 1 is a straight line structure, while a part of the auxiliary connection line 40 in the display area in fig. 5 is a broken line structure, and for the anode E1 of the light emitting device, the arrangement mode corresponds to the position of the sub-pixel, if the sub-pixels are not arranged in a row-column alignment mode, the arrangement mode of each anode E1 is not arranged in a row-column-to-column mode, and when the auxiliary connection line 40 in the display area and the anode E1 are both located at the anode layers, the auxiliary connection line 40 in the display area needs to bypass the anode E1 to avoid short circuit therebetween, which causes poor display, and therefore, the auxiliary connection line 40 in the display area does not.

That is, the auxiliary connection line 4 is electrically connected to the anode power line 3 only in the non-display region 12 through a via hole, there is no connection between the auxiliary connection line 4 and the anode power line 3 in the display region 11, since the electrical connection between the auxiliary connection line 4 and the anode power line 3 requires a via hole between the anode layer 22 and the source-drain metal layer 21, and at the connection position, it is necessary to ensure that the auxiliary connection line 4 and the anode power line 3 have a sufficient area to ensure the electrical connection effect, and therefore, if the electrical connection between the auxiliary connection line 4 and the anode power line 3 is made in the display region 11 and insulation between the auxiliary connection line 4 and the anode E1 is required to be ensured, the space occupation of other elements in the anode E1 or the source-drain metal layer 21 may be limited or.
