ABSTRACT:
A liquid crystal device includes a first substrate and a second substrate that are disposed to face each other, a first electrode and a second electrode that are disposed on a surface, which faces the second substrate, of the first substrate, a liquid crystal layer that is disposed between the first substrate and the second substrate and has liquid crystal molecules aligned in a direction parallel to the first substrate, and a pair of polarizing elements having the liquid crystal layer interposed therebetween. The liquid crystal molecules are driven by an electric field that is generated by an electric potential difference between the first electrode and the second electrode and has a component parallel to the first substrate, and the retardation of the liquid crystal layer is equal to or larger than 0.66 λ and is equal to or smaller than 0.83 λ for light having a wavelength λ of 555 nm.
