One or both of the first and second internal reflection faces each have scattering regions allowing the first illumination light from the first light source to be scattered and to exit from the first internal reflection face to outside the light guide plate, each of the scattering regions being provided with one or more pass-through regions each allowing the second illumination light from the second light source to pass therethrough.
