Abstract: A liquid crystal element is provided that can inhibit occurrence of voltage drop between one end and the other end of each electrode. A liquid crystal element (100) includes a liquid crystal layer LQ, a plurality of first arcuate electrodes (1), and a plurality of second arcuate electrodes (2). The first arcuate electrodes (1) are disposed concentrically about an optical axis (AX) of the liquid crystal element (100) and applies first voltage (V1) to the liquid crystal layer (LQ). The second arcuate electrodes (2) are disposed concentrically about the optical axis (AX) and applies second voltage (V2) to the liquid crystal layer (LQ).

Abstract: A liquid crystal element (100) includes a plurality of unit electrodes (10), a liquid crystal layer (LQ), and a plurality of wall members (WL). Each of the unit electrodes (10) includes a first electrode (1) and a second electrode (2). A voltage is applied to the liquid crystal layer (LQ) from each of the unit electrodes (10). The wall members (WL) are arranged in the liquid crystal layer (LQ). The liquid crystal layer (LQ) has a waveform retardation (RT). Two or more of a plurality of peaks (P1) in the retardation (RT) correspond to positions of respective wall members (WL).
