description Provided are a light guide plate, an area light source device, a display device, and manufacturing method for the light guide plate such that the occurrence of uneven luminance is suppressed. The light guide plate (12) is characterized in that the light guide plate has a light entrance surface (12a) through which light enters, a light exit surface (12c) intersecting with the light entrance surface (12a) and through which light is output, and an opposite surface (12b) facing the light entrance surface (12a), wherein the light entering through the light entrance surface (12a) is guided to the opposite surface (12b) side and output from the light exit surface (12c), and the refractive index Nx in a direction perpendicular to the light entrance surface (12a) is higher than the refractive index Ny in a direction parallel to the light exit surface (12c) and parallel to the light entrance surface (12a).
