  • Publication number: 20240134245
    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 (Vi) 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).

  • Publication number: 20240134234
    Abstract: This liquid crystal element comprises a liquid crystal layer LC and a plurality of unit-electrodes U1 and U2, each including a first electrode E1 that is linearly formed, a second electrode E2 that is linearly formed and receives a voltage different from that of the first electrode E1, and a resistive layer HR having higher electric resistivity than the first electrode E1 and the second electrode E2, characterized in that the resistive layer HR in each of the plurality of unit-electrodes U1 and U2 is separated from the resistive layer HR in the adjacent unit-electrodes U1 and U2 and is disposed in a region AR between the first electrode E1 and the second electrode E2 in a plan view, and at least some unit-electrodes U2 from among the plurality of unit-electrodes U1 and U2 have an auxiliary electrode EC in the region AR, the auxiliary electrode EC being linearly formed with a line width equal to or smaller than the line width of at least one of the first electrode E1 and the second electrode E2.

  • Patent number: 11860484
    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).

  • Patent number: 10598961
    Abstract: Glasses controls light that is to enter an eye. The glasses includes an optical element and a control section. The optical element includes a liquid crystal layer that refracts the light. The control section controls refraction of the light by forming an electric potential gradient in a saw-tooth shape in the liquid crystal layer through application of control voltage to the liquid crystal layer.
