Abstract
A micro shutter device and a method of manufacturing the same are provided. A barrier is provided to define a unit pixel. Film actuators are formed within the unit pixel. The film actuators are configured to be bent in opposite directions to each other from a substrate so that light passing through the substrate from an external light source is blocked in a voltage non-applied state, and to be straightened perpendicularly to the substrate so that the light is transmitted upon voltage application. Accordingly, it is possible to increase the aperture ratio and thus improve the light efficiency. Furthermore, it is possible to reduce voltage necessary to drive the film actuators and thus increase the drive speed.
