In a display lighting device in which the bottom surface of the reflector facing the light-transmitting plate is curved in a direction that approaches the light-transmitting plate as it moves away from the light source, a portion of the reflector located near the light source is curved on the bottom surface. A display lighting device characterized by being recessed with a radius of curvature smaller than the radius of curvature.
