A wide light evening backlight source module comprises a linear light source (2), a light evening reflection plate (4) and a reflection cover (3), and the linear light source (2) is provided between the reflection plate (4) and the reflection cover (3). The reflection plate (4) comprises mirror reflection regions (51, 52), mixing reflection regions (6, 6') which are comprised of mirror reflection regions (62) and diffuse reflection regions (61, 63, 63', 64), and diffuse reflection regions (71, 72, 73). The mirror reflection regions (51, 52) are positioned at the central portion of the reflection plate (4), and the mirror reflection regions (51, 52) are substantially parallel to the linear light source (2) in the longitudinal direction. The mixing reflection regions (6, 6') are provided on the both sides of the mirror reflection regions (51, 52), and the diffuse reflection regions (71, 72, 73) are provided on the outside of at least one of the mixing reflection regions (6, 6'). A wide light evening backlight source comprises at least two wide light evening backlight source modules arranged side-by-side or arranged in staggered columns and rows. |
