The present invention provides a hybrid light modulator. The hybrid light modulator of the present invention includes an element having a protrusion to diffract incident light even at an early light receiving stage and to control the diffractive angle of the light using a microactuator, unlike conventional diffractive light modulators which reflect and diffract incident light using a plurality of micromirror actuators. Therefore, the present invention realizes device miniaturization and assures easy digital operation. Furthermore, piezoelectric force may be used to provide an actuating force to the element of the hybrid light modulator. Alternatively, electrostatic or electromagnetic force may be used as an actuating force for the hybrid light modulator.
