Flat panel display using microelectromechanical device

A flat panel display comprising:

• a back substrate having a transparent electrode of a transparent electric conductor;
• a front substrate having a color filter layer;
• a support beam arranged to support the back substrate and the front substrate;
• and
• a micro-electromechanical device formed on the transparent electrode to switch light, wherein the micro-electromechanical device comprises a lower support post for supporting a horizontal shifter, an upper electrode for helping an optical switching operation, an upper support post for supporting the upper electrode, and a mask and a window formed at the horizontal shifter and the upper electrode.

A flat panel display, comprising:

• a back glass substrate having a first transparent electrode of a transparent electric conductor;
• a front glass substrate having a color filter layer and a second transparent electrode;
• a support beam arranged to support the back glass substrate and the front glass substrate;
• and
• a micro-electromechanical device formed at the first transparent electrode to switch light, wherein the micro-electromechanical device comprises:
• a rotatory shifter rotatably moved by an electrostatic force due to a voltage difference between a shifting electrode and the transparent electrode vertically spaced from the shifting electrode;
• a mask including windows formed on the rotatory shifter to block light or allow light to pass therethrough;
• and
• a support post extended from the back glass substrate, via the transparent electrode, to support and enable the rotatory shifter to move in response to the electrostatic force due to the voltage difference between the shifting electrode and the transparent electrode.
