The pressure-sensitive adhesive film of the present invention comprises a thermoplastic resin and has a thickness of 150 µm or more and 2000 µm or less, in which an amount of change in thickness of a test sample A in a predetermined compression creep test performed is 50 µm or more and 325 µm or less, and an adhesive force to a polycarbonate base material, as measured by a predetermined pressure-sensitive adhesive force measurement method, is 100 N or more. The laminate of the present invention comprises the pressure-sensitive adhesive film of the present invention, a first organic material substrate, and at least one base material of second organic material substrate and inorganic material substrate. The liquid crystal display of the present invention and the laminated glass of the present invention each comprises the laminate of the present invention. According to the present invention, there can be provided a pressure-sensitive adhesive film, a laminate comprising the pressure-sensitive adhesive film, and a liquid crystal display and a laminated glass each comprising the laminate, in which a transparency in low-temperature sticking is favorable, foaming in an end portion in low-temperature sticking is small, and adhesiveness to a resin material such as a polarization film is favorable.
