Abstract: Embodiments of the present invention disclose a reflective film, a backlight module comprising the reflective film and a display apparatus comprising the backlight module. A row of low-reflection dots are disposed on a side of a surface of the reflective film, and regions of the surface of the reflective film corresponding to the low-reflection dots have smaller reflectivity with respect to the incident light from an LED light strip disposed at a side of the row of the low-reflection dots than other regions of the surface of the reflective film with respect to the incident light from the LED light strip. The regions of the reflective film directly facing the LED are changed into low-reflection regions, in which the reflectivity is reduced. Therefore the alternate bright and dark phenomenon at light incident side is reduced or eliminated and display quality of the display apparatus is further improved.
