PURPOSE: A laser display system is provided to bend an optical fiber and control a phase of traveling light within the optical fiber by using a piezo-vibrator operated according to an electric signal. CONSTITUTION: A light source(41) is used for generating light. An optical fiber(43) is used for forming an optical waveguide of the light of the light source. An optical phase controller(44) is used for controlling a phase of the traveling light within the optical fiber. The optical phase controller includes a piezo-vibrator. The optical phase controller further includes a first and a second electrode for applying electric field to the piezo-vibrator, a fixing plate for fixing the optical fiber, and an elastic member for absorbing the vibration of the piezo-vibrator.
