Abstract
A variable stiffness film, a variable stiffness flexible display, and a manufacturing method thereof may include a lower electrode, a variable fluid, and an upper electrode. A polymer layer may be formed on the lower electrode, and a variable fluid receiving portion is patterned on the polymer layer. A variable stiffness layer is formed by putting a variable fluid in the variable fluid receiving portion. The upper electrode is formed on the variable fluid layer.
