Disclosed is a method for manufacturing a hydrogen sensor using Pd nano-wires. The method includes steps of forming an external electrode pattern on a substrate applying a first resin layer to the substrate and forming a resin layer nano-channel pattern; depositing Pd on the substrate having the nano-channel pattern, by sputtering, and removing the first resin layer to form Pd nano-wires; applying a second resin layer to the substrate having the Pd nano-wires, and forming a resin layer pattern on the external electrode pattern, at opposing ends of the Pd nano-wires, and at predetermined positions between the external electrode pattern and the opposing ends of the Pd nano-wires; and depositing conductive metal on the resin layer pattern and removing the resin layer pattern, thereby electrically connecting the external electrode pattern to the Pd nano-wires.

A triodic rectifier switch includes at least one first diode connected to a data line, at least two second diodes connected to a load capacitor, a resistor having one terminal connected to a scan line and the other terminal connected to a node between the first diodes and the second diodes. The triode rectifier switch further includes at least one reset diode having one terminal connected to a node between the first and second diodes and the other terminal connected to a reset line. The second diodes are serially-connected to each other.
