摘要：
A light guide plate and a manufacturing method thereof, a backlight module, and a display device are provided. The light guide plate includes a light incident surface, a light reflection surface, and a light-emitting surface; the light reflection surface includes a first prism structure array, the first prism structure array includes first prisms arranged in sequence in a first direction, and the first direction is perpendicular to the light incident surface; the first prism structure array is configured to enable light emitted from the light incident surface to be emitted toward the light-emitting surface; and the light-emitting surface includes a second cylindrical structure array, the second cylindrical structure array includes second cylindrical structures arranged side by side in a second direction, the second direction is perpendicular to the first direction, and a first plane including the first direction and the second direction is perpendicular to the light incident surface.
