Abstract

The present invention aims to provide an interlayer film for laminated glass which prevents a double image phenomenon in a specific area of laminated glass and enables display of high contrast images at a luminance within a certain range. The present invention also aims to provide a laminated glass including the interlayer film for laminated glass. The present invention relates to an interlayer film for laminated glass, having a multilayer structure including a luminescent layer and a resin layer on at least one surface of the luminescent layer. The luminescent layer contains a thermoplastic resin, a plasticizer, and a luminescent material. The resin layer contains a thermoplastic resin and a plasticizer. The interlayer film for laminated glass has a wedge-shaped cross-sectional shape. The luminescent layer has a difference between the maximum thickness and the minimum thickness of 100 μm or less.
