Abstract:
A laminated glass includes first and second glass plates arranged on vehicle interior and exterior sides, respectively; and an intermediate film located between the glass plates, and configured to be bonded to the glass plates. The laminated glass has a display area used for a head-up display. The display area includes an area having a cross section with a wedge shape. A thickness of an upper edge side portion of the display area is greater than that of a lower edge side. In at least a part of the area having a cross section with a wedge shape, a value of the wedge angle varies depending on a position of measurement in the vertical direction. A viewing angle of the display area is 2 degrees or more. A maximum amount of deviation in measured values of the wedge angles from a linear approximation line is 0.2 mrad or less.
