Abstract
A disclosed laminate structure is capable of having its surface free energy changed with a small amount of UV irradiation. The invention also discloses a method of manufacturing the laminate structure; an electronic device having the laminate structure; an electronic device array having a plurality of the electronic devices; and a display apparatus having the electronic device array. The laminate structure includes a substrate, a wettability variable layerdisposed on the substrate, and a conducting layerpatterned on the wettability variable layer. The wettability variable layerincludes a material whose critical surface tension varies upon application of energy. The material with variable critical surface tension has a main chain and a side chain. The side chain has two or more sites of which the bond is cleaved upon absorption of energy.
