Abstract
A light emitting assembly, a backlight source and a display panel are provided. The light emitting assembly includes: a circuit board, at least one LED on the circuit board; the at least one LED has a main light emitting face substantially parallel to the circuit board and An oblique side light emitting face, the side light emitting face being located between the main light emitting face and the side light emitting face; a reflective film between the circuit board and the at least one LED; an acute angle is formed between the main light emitting face and the side light emitting face, and the side light emitting face is configured such that light emitted by the side light emitting face is directed away from the LED and is directed toward the circuit board, the reflective film being configured to reflect light emitted by the side light emitting face.
