A window or other component may have glass layers and an interposed polymer layer in which a textured light-scattering layer with a diffuse reflectivity is embedded. The textured light-scattering layer may have a textured polymer carrier film coated with a partially reflective layer such as a metal layer. The polymer carrier film may be textured to cause gaps to form within the partially reflective layer. The gaps may be patterned to form ohmic heating current paths or other signal paths through the partially reflective layer. The partially reflective layer may also serve as an electrode in a light modulator such as a liquid crystal light modulator or other light modulator. Images may be projected onto the textured light-scattering layer. The light-scattering layer may also help extract light from a light guiding layer adjacent to the partially reflective layer.
