Abstract
A backlight module includes a light-emitting element, a quantum dot film, an optical film and a light adjusting element. The light-emitting element is adapted to emit a blue light. The quantum dot film is adapted to converting a first portion and a second portion of the blue light into a red light and a green light, respectively. The optical film is disposed on the quantum dot film. The light adjusting element is disposed between the optical film and the quantum dot film. The light adjusting element has a first surface and a second surface respectively facing the quantum dot film and the optical film. The first surface has multiple first optical microstructures. The first optical microstructures include multiple cones protruding toward the quantum dot film. Moreover, a display apparatus including the backlight module is also provided.
