The first substrate and the second substrate of the element are set in an orientation process direction that ensures generation of a first orientation state, and a chiral material that generates a second orientation state is included in the liquid crystal layer. The layer transitions from the second orientation state to the first orientation state when an electric field of a layer thickness direction is applied. The layer transitions from the first orientation state to the second orientation state when an electric field of a direction perpendicular to the layer thickness direction is applied. And the layer returns to the second orientation state when an orientation change is generated according to the strength of the electric field when an electric field of the perpendicular direction is applied.

Abstract: To prevent damage in an electro-optical device that uses electrochromic material. The device includes electro-optical elements and a driving device that applies a driving voltage to the electro-optical elements. The driving device applies a first DC voltage of a positive polarity that cyclically repeats a first voltage and a second voltage that is lower than the first voltage, or a second DC voltage of a negative polarity that cyclically repeats a third voltage and a fourth voltage that is higher than the third voltage, to the electro-optical elements. According to the driving device, when the first DC voltage is applied to one and the second DC voltage is applied to the other electro-optical elements adjacent in the planar view, the first and the second DC voltages are supplied by time division so that the applied period of the first voltage and the third voltage do not overlap.
