ABSTRACT:
A process for producing planar dimmer comprising a transparent base, a dimming part, capable of dimming, disposed on the base, the dimming part comprising a first electrode layer formed on the base, a second electrode layer set facing the first electrode layer, a coloring part, disposed between the two electrode layers, and colors or discolors in response to the stimulus from the two electrode layers, and a conducting part disposed between the base and the first electrode layer in such a way as to be in contact with the first electrode layer in order to apply a uniform voltage throughout the first electrode layer.
The process includes forming paint stripes, electrolessly plating a metal film over each of the stripes, forming an electrode layer over the metallized stripes, and forming a color-forming layer over the electrode layer.
