Abstract: The present application discloses a lens assembly, a display module, and an electronic device. The lens assembly includes a first lens including a first surface and an opposite second surface and a semi-transmissive and semi-reflective film arranged on the first surface. The semi-transmissive and semi-reflective film includes a modulation film layer and a medium film layer, the modulation film layer being arranged on the first surface of the first lens, and the medium film layer being arranged on a side of the modulation film layer away from the first lens. The medium film layer and the modulation film layer are configured to cooperatively adjust a refractive index of the semi-transmissive and semi-reflective film, so as to allow circularly polarized light incident on the semi-transmissive and semi-reflective film at different incident angles to remain as the circularly polarized light after entering the first lens.
