PROBLEM TO BE SOLVED: To contrive the proper selection adjustment and chromaticity variety of a sliding screen face by using a polymer distribution liquid crystal on the sliding screen face, and performing electric control such as amplitude modulation and pulse width modulation of applied voltage on the distribution liquid crystal. SOLUTION: A polymer distribution liquid crystal sheet is made structure sandwiching a liquid crystal on opposite transparent electrode sheets, two electrodes are removed on one sheet by contact or a connector to be exchanged. Transmission and scattering of the distribution liquid crystal 1 are controlled by an indoor and outdoor illuminance difference, in daytime transmission is performed to perform daylighting in a room, and in the night time it is unnecessary to close a sliding screen by controlling it so as to be opaque. In the case, even when the sliding screen door is at a high place, opening and closing are unnecessary, daylighting is controlled and adjusted by remote control of a radio wave and an infrared ray. Furthermore, light wavelength is detected by an optical detector 7 with a wavelength filter. Thereby the chromaticity of light scattering controlling the transmission and scattering is adjusted to change a sliding screen color so as to obtain intelligent effect.
