Abstract: An illumination device (10) is provided with the following: light sources (11); a light-guide member (12 (13)) that includes a light entry region (Is) and a light exit region (Os) which emits planar light; light entry portions (13a) that are formed in the light entry region (Is) and that oppose the light sources (11); and bright line suppression portions (20) that are formed in the areas between the light entry portions (13a) at the front side of the light entry region (Is), and that include bright line suppression prisms (21) which have a shape that changes the angle of the light emitted in a direction spreading out from the light sources (11) to a direction closer to the optical axes.
