1. A transparent display substrate, comprising:
at least one pixel unit, wherein each of the at least one pixel unit comprises at least three sub-pixel groups emitting light of different colors respectively, each of the sub-pixel groups comprises at least two sub-pixels, and each of the sub-pixels comprises:
a first electrode;
a light-emitting structure block located on the first electrode; and
a second electrode located on the light-emitting structure block,
wherein in the at least one pixel unit, two first electrodes of two adjacent sub-pixels in one of the sub-pixel groups are electrically connected by a first connecting portion, and two first electrodes of two sub-pixels in another one of the sub-pixel groups are electrically connected by a second connecting portion, wherein the second connecting portion connects two sub-pixels in the another one of the subpixel groups and is at least partially surrounding sides of at least two sub-pixels of other sub-pixel groups, and
the first connecting portion and the second connecting portion are located in a same layer.
