Abstract

Disclosed is a touch control device, comprising a substrate, a plurality of sensing units, an insulating layer, an electric bridge, a protection layer, a supporting part, an element layer and a glue part. A plurality of sensing units are disposed on the substrate in an interval between two of sensing units to expose portions of the substrate. The insulating layer covers the exposed substrate. The electric bridge covers the insulating layer, and two ends of the electric bridge are respectively connected to two sensing units among the plurality of sensing units. The protection layer covers the electric bridge and the sensing unit. The supporting part covers the protection layer. The element layer is disposed on the supporting part. As a result, an accommodating space is formed therebetween. The accommodating space is filled up with the glue part to glue the protection layer and the element layer.
