Lighting device and display device

A lighting device comprising:

• a light guide plate having a light exit surface having a substantially circular shape and a light entrance surface extending along an entire periphery of an outer edge of the light exit surface;
• a first light source opposite the light entrance surface;
• and
• a second light source opposite the light entrance surface, the second light source that is connected in parallel to the first light source or connected to a power supply different from a power supply that is connected to the first light source, the second light source arranged opposite from the first light source with having a center of the light exit surface therebetween
• the first light source includes first light sources that are arranged in a circumferential direction of the light entrance surface,
• the first light sources are connected in series,
• the second light source includes second light sources that are arranged in the circumferential direction of the light entrance surface, and
• the second light sources are connected in series;
• the first light sources and the second light sources are at least included in light sources,
• a total number of the light sources is an odd number,
• the light sources are arranged at equal intervals in an annular shape having a center corresponding to the center of the light exit surface, and
• a value obtained by (R1 * circumference of ratio)/N is 10 mm or less, R1 is a distance between each of the light sources and the center of the light exit surface, and N is the total number of the light sources.
