Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a lighting device which is thinned and relaxes steep luminance changes in boundary portions between divided regions having different light emission luminances, and also to provide a display device using the same. SOLUTION: Each of light emitting elements 10 in each of light source modules 11 has an optical element 28 arranged respectively according to a chip 25. By refracting light from the corresponding chip 25 by each optical element 28, a luminance of light radiated right above the light emitting element 10 adjacent to the light emitting element 10 is set larger than a luminance of light radiated right above from the chip 25. When nine light emitting elements 10 in the light source module 11 emit light, each light emitting element 10 is prevented from lighting brightest right above each light emitting element 10, the luminance is gradually reduced in a line direction, a row direction or the like as it separates from a center region 11-A of the light source module 11, and, thereby, the steep luminance changes in the boundary portions between the light source modules 11 having different light emission luminances is relaxed.
