Abstract:
Provided are a film (1), a backlight module, and a display device. The film (1) comprises: a first main body (10) having a plate-shaped structure; a protruding portion (20) protruding, within a plane where the first main body (10) is located, from an edge of the first main body (10); and a positioning structure (30) intersecting a surface of the protruding portion (20). The positioning structure (30) comprises a second main body (301) and one or more openings (302). The second main body (301) comprises a blocking portion (3011) and a connection portion (3012). The blocking portion (3011) is connected to the protruding portion (20) by means of the connection portion (3012). The one or more openings (302) are arranged between the blocking portion (3011) and the protruding portion (20). The film (1) can reduce occurrence of a structural defect and poor image quality in a backlight module resulting from jump displacement of an optical film, thereby improving structural stability and quality of a backlight source.
