Abstract
A device for controlling transmittance of light therethrough includes first and second transparent substrates which are spaced from each other. The first substrate has at an end portion thereof a notch. First and second transparent electrode layers are respectively coated on inner surfaces of the first and second substrates for defining a space therebetween. The first layer is partially cut off so as to conform to a periphery of said notch. An electro-optically responsive material substantially fills up the space. The material is made so as to allow transmittance of light therethrough to change in response to voltages applied between the first and second layers. A terminal is received in said notch and said space, and is sized so as to be biased against the first substrate and the second layer so as to ensure an electrical contact between the terminal and the second layer.
