The projection surface includes a transparent screen having a transparent substrate and at least one electrically conductive coating with at least one functional layer on at least one surface of the transparent substrate.

Provided is an interlayer film for laminated glass capable of suppressing the discoloration by the light and heat in an interlayer film including a resin layer colored with a coloring agent. The interlayer film for laminated glass according to the present invention has an infrared reflective layer, and a first resin layer containing a thermoplastic resin, the first resin layer is arranged on a first surface side of the infrared reflective layer, the infrared reflective layer has a first maximum reflection wavelength at a wavelength of 350 nm to 450 nm, and a second maximum reflection wavelength at a wavelength of 800 nm or more, each of reflectance at the first maximum reflection wavelength and reflectance at the second maximum reflection wavelength is 15% or more, and the first resin layer contains a coloring agent.

Functional layers do not have a good performance at lower temperatures. This limitation is overcoming by combining the functional layers with a resistive heating circuit. The heating circuit uses minimal power to maintain the glazing at or above the temperature required for acceptable operation.
