The liquid crystal 1 is transparent and transmits light when it is not in operation, and displays d when it is in operation.
'It has the property of reflecting and scattering light only when it turns. For example, it is a dust-host type liquid crystal to which a dye is added, and displays colored characters and the like by applying voltage through a transparent electrode plate 2 for driving the liquid crystal. Also, what is the threshold voltage of liquid crystal 1? It is about the same level. LCD 1. It is desirable that the transparent electrode plate 2 for driving the liquid crystal and the transparent electrode plate 3 for the solar cell have good light transmittance, and in particular, have good transmittance of light with a short wavelength.
