Abstract
The present invention relates to an interference optical modulator and a display apparatus having the same. The display apparatus includes a metal thin film and a dielectric multiple thin film spaced apart from the metal thin film. The display apparatus may realize colors by changing an interval between the metal thin film and the dielectric multiple thin film, and may realize a black color by applying a voltage to each respective sub-pixel.
