LIGHT DEFLECTOR, LIGHT DEFLECTING DEVICE, AND LIQUID CRYSTAL DISPLAY DEVICE USING LIGHT DEFLECTOR AND LIGHT DEFECTING DEVICE

A light deflector (10) that deflects inputted light is provided with a light deflecting element (101), which deflects the inputted light by modulating internal refractive index distribution, and the light inputted to the light deflecting element (101) is outputted from the light deflecting element (101) after having the light pass through the light deflecting element (101) a plurality of times.
