Abstract: An illumination apparatus has a first longitudinal light source section that includes a first substrate and a second substrate on which a plurality of light sources are arranged in a line in the longitudinal direction, and a second longitudinal light source section that includes a third substrate and a fourth substrate on which a plurality of light sources are arranged in a line in the longitudinal direction. The first longitudinal light source section and the second longitudinal light source section are arranged side by side in the short direction. The plurality of light sources on the first longitudinal light source section and the plurality of light sources on the second longitudinal light source section are displaced from each other in the longitudinal direction of the first longitudinal light source section and the second longitudinal light source section.
