A method is disclosed for manufacturing a very fast micro light valve of the type used to control the passage of light through a pixel. The method comprises preparing a substrate, which can be made of glass, and forming transparent electrodes on the main surface of the substrate. Next an insulating layer is deposited on the substrate and a first sacrificial layer is formed on the insulating layer. A pattern shifting element layer is formed on the first sacrificial layer and a second sacrificial layer is formed on the substrate and provided with a shifting element layer. After portions of the sacrificial layers are removed by etching to form a frame contact portion, a patterned frame layer is formed on the frame contact portion. Then a frame and a shifting element capable of moving in the frame under an applied external electrostatic force are formed by removing the remaining sacrificial layers.
