1. A light guide panel comprising:
a base substrate comprising a top surface, a bottom surface opposing the top surface, and side surfaces connecting the top and bottom surfaces, at least one side surface among the side surfaces defining a light incident surface; and
a light-scattering layer provided on at least one of the top and bottom surfaces of the base substrate, the light-scattering layer comprising:
a first central portion distant from the light incident surface;
a second peripheral portion located closer to the light incident surface than the first central portion and encompassing the first central portion, the thickness of the first central portion of the light-scattering layer being substantially equal to the thickness of the second peripheral portion of the light-scattering layer; and
a matrix forming a first layer provided on the base substrate having first light-scattering particles dispersed in the matrix, the first light-scattering particles having a first average particle size range, a density of the first light-scattering particles in the first central portion being higher than a density of the first light-scattering particles in the second peripheral portion,
wherein the density of the first light-scattering particles is less than 5 wt. %, the transmissivity of the light guide panel is higher than 80%, and the haze of the light guide panel is smaller than 10%; and
wherein the surface roughness of the light-scattering layer is equal to or less than 1 μm.
