Title: INTERLAYER FOR LAMINATED GLASS, AND LAMINATED GLASS
Abstract:
Provided is an interlayer for laminated glass, said interlayer being able to suppress both a reflected double image and a transmitted double image in a laminated glass. An interlayer for laminated glass according to the present invention is used in a laminated glass, said laminated glass being a head-up display, has a display correspondence region that corresponds to a display region of the head-up display, and has one end, and another end on the opposite side from the one end. The thickness of the other end is greater than the thickness of the one end, and when the amount of change in thickness from the one end side to the other end side is measured, with points in the display correspondence region at intervals of 2mm as the centers, and at a distance of 80mm in a direction connecting the one end and the other end, the absolute value of the difference between the maximum value of the measured values of the amount of change in thickness and the minimum value of the measured values of the amount of change in thickness is 32μm or less. The wedge angle of a region that is more to the other end side than the display correspondence region is smaller than the wedge angle of the display correspondence region.
