A liquid crystal light deflector comprises: a first electrode layer including line electrodes; a second electrode layer which is a common electrode; and a liquid crystal layer forming an electric prism by using liquid crystal molecules in accordance with an electric field formed between the electrode layers. The orientations of the liquid crystal molecules are reset by the electric field formed between the line electrodes of adjacent channels in the first electrode layer. 액정 광 편향기는 라인 전극들을 포함하는 제 1 전극층, 공통 전극인 제 2 전극층 및 전극층들 사이에 형성된 전계에 따라 액정 분자들을 이용한 전기적 프리즘을 형성하는 액정층을 포함하고, 액정 분자들의 배향들은 제 1 전극층 내 인접한 채널들의 라인 전극들 사이에 형성된 전계에 의해 리셋된다.
