Classification: CPC nan | IPC G

Claim 1:
2. A light control device comprising:
a first liquid crystal cell comprising a first liquid crystal layer between a pair of substrates;
a second liquid crystal cell comprising a second liquid crystal layer between a pair of substrates; and
a polarization conversion element disposed between the first liquid crystal cell and the second liquid crystal cell,
wherein one of substrates in each of the first liquid crystal cell and the second liquid crystal cell, comprising:
an insulating substrate; and
first to fourth electrodes arranged in order on the insulating substrate and formed in a strip shape,
a potential difference between the first electrode and the second electrode, a potential difference between the second electrode and the third electrode, and a potential difference between the third electrode and the fourth electrode are different from each other,
the first liquid crystal cell is configured to scatter a first polarization component having a polarization plane in a first direction, of incident light,
the polarization conversion element is configured to convert a second polarization component having a polarization plane in a second direction intersecting the first direction, of light transmitting through the first liquid crystal cell, into the first polarization component, and
the second liquid crystal cell is configured to scatter the first polarization component, of the light transmitting through the polarization conversion element.
