Abstract: A transparent display includes a transparent substrate, a wiring layer, a plurality of light-emitting package units, and a plurality of connecting elements. The wiring layer is disposed on a surface of the transparent substrate. Each of the light-emitting package units includes a micro-substrate, frontward light-emitting elements, backward light-emitting elements, and a sealant. The micro-substrate has a first surface facing away from the transparent substrate and a second surface facing the transparent substrate. The frontward light-emitting elements are disposed on the first surface of the micro-substrate, in which the micro-substrate is configured to block the light from the frontward light-emitting elements toward the transparent substrate. The backward light-emitting elements are disposed on the second surface of the micro-substrate. The sealant covers the micro-substrate, the frontward light-emitting elements, and the backward light-emitting elements. The connecting elements electrically connect the light-emitting package units to the wiring layer, respectively.
