The invention provides a light guide plate, a light guide plate manufacturing method, a backlight LED module, a display and a panel lamp. The light guide plate includes a light guide plate base material, the light guide plate base material is provided with a light inlet surface, a light outlet surface and a bottom surface, wherein the light outlet surface is opposite to the bottom surface, in addition, the light outlet surface or the bottom surface is provided with an ink film layer, and light guide particles are distributed in the ink film layer according to a predetermined law. The ink film layer containing the light guide particles is printed on the light outlet surface, the light guide particles in the ink film layer are distributed according to the law that the density of the light guide particles gradually increases in the direction from the position close to a light source to the position away from the light source, in this way, an auxiliary diffusion plate or an auxiliary diffusion film is omitted, light loss is reduced by 10% or so, and the product cost is lowered; moreover, as a linear light source is directly converted into the surface light source, uniform outlet light brightness which cannot be achieved in the prior art can be achieved through the light guide plate, and the requirement of large-size light guide plates and complex optical design requirements can be satisfied.
