1. A light control film, comprising:
a first base material layer;
light blocking members disposed on a side of the first base material layer, wherein light transmissive regions are defined between the light blocking members;
light transmissive members filled in the light transmissive regions;
light control members disposed on the light transmissive members, corresponding to the light transmissive regions, and configured to decrease light emission angles of light passing through the light transmissive members, and
wherein the light control film further comprises:
a first electrode layer disposed between the first base material layer and the light blocking members;
a viewing-angle transformation layer disposed on a side of the light blocking members and the light control members away from the first electrode layer;
a second electrode layer disposed on a side of the viewing-angle transformation layer away from the light control members; and
a second base material layer disposed on a side of the second electrode layer away from the viewing-angle transformation layer;
wherein the viewing-angle transformation layer is configured to allow light passing through the viewing-angle transformation layer to not be refracted, when a voltage difference exists between the first electrode layer and the second electrode layer; or the viewing-angle transformation layer is configured to allow the light passing through the viewing-angle transformation layer to be refracted, when the voltage difference does not exist between the first electrode layer and the second electrode layer.
