Abstract
A light control element includes a first substrate, a first electrode, a first liquid crystal layer, a second electrode, a second substrate, a first internal conductive object, a first intermediate conductive object and a second internal conductive object. A peripheral area of the second substrate has a first through hole. The first internal conductive object is disposed in a first through hole of the second substrate. The first intermediate conductive object is disposed between the peripheral area of the second substrate and the first substrate, and is electrically connected to the first electrode and the first internal conductive object. The peripheral area of the second substrate further has a second through hole. The second internal conductive object is disposed in the second through hole of the second substrate and is electrically connected to the second electrode.
