A substrate structure, comprising a carrier substrate and a flexible substrate disposed on the carrier substrate, the substrate structure further comprising a bonding layer interposed between the carrier substrate and the flexible substrate, or more than one bonding layer parallel interposed between the carrier substrate and the flexible substrate, wherein the bonding layer or each of the more than one bonding layer comprises an electroviscosity layer, viscous strength of which changes under effect of electric field, the electroviscosity layer is disposed on a contact surface between the bonding layer and the flexible substrate, wherein the bonding layer or each, of the more than one bonding layer further comprises a base and an adhesive, the base interposed between the electroviscosity layer and the adhesive, and the adhesive disposed on a contact surface between the bonding layer and the carrier substrate, and wherein the adhesive is another electroviscosity layer.
