1. A transparent display panel, comprising:
a light transmissive substrate, with a surface;
a plurality of first pixels arranged on the surface to form an image in a first direction;
a plurality of second pixels arranged on the surface to form an image in a second direction, wherein a pitch of the first pixels is different from a pitch of the second pixels;
a plurality of top-emitting micro light emitting diodes for emitting rays in the first direction, the top-emitting micro light emitting diodes being disposed on the surface and arranged in the first pixels;
a plurality of bottom-emitting micro light emitting diodes for emitting rays in the second direction, the bottom-emitting micro light emitting diodes being disposed on the surface and arranged in the second pixels, wherein each of the bottom-emitting micro light emitting diodes comprises an epitaxial structure and a light shielding component, the epitaxial structure has an upper surface and a lower surface, the lower surface faces the light transmissive substrate, and the light shielding component is disposed on the upper surface to shield the rays emitted from the bottom-emitting micro light emitting diodes towards the upper surface; and
a plurality of pixel-solar cells, disposed on the surface and arranged in the second pixels.
