Abstract
A flat panel display device displays an image using a micro-shutter electrode and a diffusive reflection layer. The display device has a wide viewing angle and reduces a loss of light to thus improve light efficiency. In addition, gray levels can be determined by an electrostatic force between the pixel electrode and the micro-shutter electrode. An opening/closing operation of the micro-shutter electrode is fast so that the response speed can be improved.
