A lightweight glass plate includes a first glass plate, a second glass plate and an intermediate layer that connects the first and the second plates together. The lightweight glass plate further includes at least one connection element that allows the lightweight glass plate to be connected to an abutting component. The connection element is embedded into the intermediate layer in an edge area of the lightweight glass plate and the intermediate layer extends to surfaces located between the connection element and the glass plates. The lightweight glass plate is preferably used in the preparation of elevator doors and/or car walls. The lightweight glass plates are lightweight and can transfer large forces.
