Light guide structure, backlight module and display device

The invention discloses a light guide structure, a backlight module and a display device in order to solve the problem that the display device is uneven in luminance due to the fact that shadows are formed at splicing portions of light guide plates after multiple light guide plates are spliced. The light guide structure comprises a plurality of mutually spliced light guide plates, and the side face, serving as a splicing face, of each light guide plate is provided with a light scattering structure. According to the light guide structure, the backlight module and the display device, the light scattering structures are arranged on the splicing faces of the light guide plates, so light in the light guide plates can be scattered at the splicing portions, furthermore, the luminance at the splicing portions is improved, and shadows formed at splicing portions of the light guide plates can be avoided; when the light guide structure is applied to the display device, the luminance of the display device is even.
