Abstract:
Provided are a transmittance variable window that maximizes user convenience and a moving means including the same including a first substrate and a second substrate facing each other; a first electrode and a first alignment layer sequentially stacked on a surface of the first substrate, the surface facing the second substrate; a second electrode and a second alignment layer sequentially stacked on a surface of the second substrate, the surface facing the first substrate; a liquid crystal layer interposed between the first alignment layer and the second alignment layer; a first polarizing plate disposed on a surface of the first substrate, the surface facing away from the second substrate; and a second polarizing plate disposed on a surface of the second substrate, the surface facing away from the first substrate, wherein if a potential difference applied between the first electrode and the second electrode is V, considering an incidence light incident on any one of the first polarizing plate and the second polarizing plate and a transmitting light passing through the other one of the first polarizing plate and the second polarizing plate, a transmittance defined as a ratio of the intensity of the transmitting light to the intensity of the incidence light varies between a minimum transmittance and a maximum transmittance as V changes, and an initial transmittance when V is 0 is greater than the minimum transmittance and less than the maximum transmittance.
