Abstract
The present disclosure provides a light homogenizing structure, a front light source and a display device. The light homogenizing structure comprises a transparent substrate and a plurality of light homogenizing units arranged on a surface of the transparent substrate facing the display panel; wherein a surface of each of the light homogenizing units away from the transparent substrate is a reflective surface tilted relative to the transparent substrate, light rays emitted from the light-emitting unit facing a light entry surface of the light homogenizing structure are incident into the display panel after being reflected on the reflective surface, the light entry surface is other than a surface of the light homogenizing structure facing the display panel and its opposite surface, and an orthographic projection of one of the light homogenizing units on the display panel is located on a border between pixels of the display panel.
