Backlight module and display device

A backlight module, comprising:

• a light source component;
• and
• an illumination rendering film located on a light exiting side of the light source component,
• wherein the illumination rendering film comprises a plurality of dimming units arranged in an array,
• each of the dimming units is configured to receive a dimming signal and change a transmittance of the each of the dimming units according to the dimming signal,
• wherein each of the dimming units comprises a transmittance adjustment layer and a control electrode for controlling the transmittance adjustment layer, the control electrode is configured to generate an electric field for controlling a transmittance of the transmittance adjustment layer according to the dimming signal,
• the transmittance adjustment layer comprises a polymer stabilized liquid crystal layer and two alignment layers respectively located on two sides of the polymer stabilized liquid crystal layer, and
• the polymer stabilized liquid crystal layer includes liquid crystal molecules in a continuous phase and a polymer monomer dispersed in a network form.
