发明名称 LIGHTING SYSTEM AND DISPLAY DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a lighting system capable of illumination by reducing luminance unevenness while preventing deterioration of strength in structure and deterioration of productivity.SOLUTION: A backlight unit 20 being a lighting system is provided with: LEDs 32 that are arranged on one face of a substrate 31 as a plurality of light sources; and a diffusion plate 22 that is arranged on the irradiation side of light of the LEDs 32 for diffusing the light emitted by the LEDs 32. The plurality of LEDs 32 include: a plurality of main LEDs 32a for lighting up with a prescribed luminance; and a plurality of correction LEDs 32b which are arranged between two main LEDs 32a to light up with a luminance lower than the luminance of the main LEDs 32a. Thereby, the correction LEDs 32b are lighted up in a region of a low luminance that may occur between the two main LEDs 32a.
