Abstract:
Disclosed are a backlight module structure, a display panel and a display device. The backlight module structure comprises a light source (300), and a first substrate (100) and a second substrate (200) which are fitted opposite each other, wherein the first substrate (100) comprises a reflection structure (110); the second substrate (200) comprises a light guide plate (210) and a light selection layer (220) which are laminated; the light selection layer (220) is located on the side of the light guide plate (210) that is close to the reflection structure (110), and the refractive index of the light selection layer (220) is less than the light refractive index of the light guide plate (210); the light selection layer (220) is provided with several light extraction holes (220a) penetrating the light selection layer (220); and the light source (300) is located at one end of the light guide plate (210). The reflection structure (110) in the first substrate (100) reflects light extracted from each of the light extraction holes (220a), and the light passes through the light guide plate (210) at a small incident angle, thereby forming a surface light source with uniform light intensity.
