ABSTRACT:
Provided are an optical shutter including charged particles, and a display apparatus using the optical shutter. The optical shutter may block or transmit light by changing the position of the charged particle according to a direction an electrical field is applied. Also, a new type of display apparatus may be realized by using the optical shutter as a pixel of the display apparatus. The charged particles react very quickly to the change of the electrical field, and thus, a display apparatus having high operational speed may be realized.
