Abstract

A laminated glass structure is provided containing at least one glass sheet, a plastic layer provided at the bonding surface of the glass sheet, and a functioning layer having single-or multi-layered films between the bonding surfaces of the glass sheet and the plastic layer, with the functioning layer having a controlling layer in contact with the plastic layer, which contains as the major component an oxide including Cr and at least one of Ti, Zn, Sn, Ni, Zr, Al, Si, Mg and Fe, and wherein the controlling layer has an atomic ratio of Cr to atoms other than oxygen of 60% or lower, and the film thickness of the controlling layer is 10 .ANG. to 500 .ANG..
