Abstract

PURPOSE:To obtain a more colorful dimming controller than usual by placing a color filter at an interval from a planar dimming element of a dimming controller using the planar dimming element for controlling a transparent state and a scattering state by an electric field. CONSTITUTION:As for a planar dimming element used for this dimming controller, it will suffice that said element is a planar element by which light is varied to a transparent and a scattering state. Also, for instance, a color filter 12 and a color filter 13 are used jointly. In this case, when it has been looked at from an observer, when the planar dimming element is in a scattering state, a color of the second color filter 13 which has been placed so as to adhere almost closely to the reverse side locks whitish, and when the planar dimming element is in a transmission plate, a color mixture of the color filter 12 and the second color filter 13 is seen. When the second color filter 13 is placed so as to adhere closely to the planar dimming element 11, the variation of the color becomes large by switching the transmission and scattering.
