ABSTRACT:
The present invention provides, in a HUD device employing a high-functional windshield such as a sound-insulation glass having a multi-layer interlayer, a windshield for a vehicle which does not produce double images and has excellent visibility without deteriorating functionality of the windshield. In a laminated glass having a multi-layer interlayer having a wedge-shaped thickness profile sandwiched by glass sheets, the multi-layer interlayer has layers having different hardness, the thickness of first resin layers having high hardness is at least 0.3 mm in a region within 400 nm from a lower side, which prevents the generation of optical distortion of the laminated glass and efficiently prevents double display images.
