A dual fuel heating system can be used in a gas appliance. The compliant mechanism may be used in applications that require high precision alignment and where the relative location of coupled components must be variable or adjustable. The photoelectric conversion unit, the thin film transistor, the capacitance and the thin film transistor are formed by a same layer configuration, and is each formed at least by a lower electrode or a gate electrode, a gate insulation film and a semiconductor layer and separated by a protective layer from the phosphor. The post contact etch dielectric layer is selectively removed from the contacts to leave a dielectric liner on sidewalls of the PMD layer. An unwinding-roll holding part vertically holds the film unwinding roll on one side of the main body and includes a stationary locking step, a movable locking step, and an elastic spring.
