In this process, the thickness and form of the transparent substances 13 are determined so that once the reflected light and multiple reflection light 6 on the interfaces such as between transparent substrates 3 and electrode layers 2 enter the transparent substances 13, the light can not exits or be reflected on the light-entering faces and enter again the precursor 1 of the light-controlling layer. この時、透明基板3と電極層2、等の界面での反射光及び多重反射光6は、透明性物質13へ入射した後、その入射面から射出、又は反射し、調光層前駆体1へは入射しないように、透明性物質13の厚みや形状が選定されている。 - 特許庁
