  • Publication number: 20110235147
    Abstract: The display apparatus including a microelectromechanical (MEMS) shutter is disclosed. The MEMS shutter is shifted by the switching element in a horizontal direction corresponding to the light control area to turn on or turn off the light control area. A first slit transmits light generated from the light source to the MEMS shutter of a first substrate and a second slit of a second substrate corresponding to the first slit provides apertures by overlapping the first slit and the second slit. The apertures of the MEMS shutter are distributed on a two dimensional plane and form a geometrically symmetric pattern that are capable of enhancing light-use efficiency.
