Abstract
A light control film to be bonded to a panel member for a vehicle includes film substrates, conductive layers, and a liquid crystal layer. The conductive layers are on surfaces of the film substrates opposed to each other, respectively. The liquid crystal layer is sandwiched between conductive layers. The light control film is switchable between a first state with a first haze percentage and a second state with a second haze percentage that is lower than the first haze percentage. Each film substrate includes at least an acrylic imide layer made of acrylic imide. Each conductive layer includes a thin silver film or a copper wire mesh.
