A display device includes a substrate, a driving circuit structure and at least one light emitting device. The driving circuit structure is disposed on the substrate and has at least one driving thin film transistor. The at least one light emitting device has a first connecting post and a second connecting post thereby being disposed on the driving circuit structure, and the at least one light emitting device is electrically connected to the at least one driving thin film transistor through the first connecting post. The at least one driving thin film transistor includes a channel layer, and a distance between the first connecting post and the second connecting post is greater than a channel length of the channel layer.
