PURPOSE:To improve the safety and light-conditioning function of a light- conditioning glass, by using a pair of glass plates as light-conditioning glass substrates, making one or both of the glass plates with a laminated glass and equalizing the curvature of the contacting surface of the laminated glass to that of the opposite faces of the substrates. CONSTITUTION:Three or more glass plates are stacked one upon another and subjected to bending process at the same time. At least two glass plates consisting of the glass plate positioning at the top or bottom layer in the bending operation and the glass plate adjacent to the above plate are laminated to form laminated glass plates via the mutual contacting face in the bending operation (e.g. 1-7-2, 3-8-4, 7 and 8 are interlayers). The glass plate constituting the laminated glass is placed opposite to the contacting surface of another glass plate in bending operation (e.g. 2 and 3) to form a pair of substrates (e.g. 5 and 6). A light-conditioning layer (composed of a light-conditioning film 9, an electrolyte 10 and a sealing material 11) is inserted between the substrates 5 and 6.
