The present disclosure discloses a microlens array film including a film-shaped main body layer and a plurality of microlenses arranged on the top of the main body layer, the top surface of the microlens is a cambered surface, and the projected image on the main body layer is rectangular. The disclosure also discloses a display module. The microlens array film of the present disclosure includes a plurality of microlenses arranged in an array, the top surface of the microlens is a cambered surface and has a rectangular projected image on the film like main body layer. The filling ratio of the microlens array reaches 100%, which can fully cover all the sub-pixels.
