The planar lighting apparatus includes a planar light source including light emitting elements, a first housing, a light emitting surface divided into light emitting regions, and a first temperature sensor disposed inside of the first housing. The planar lighting apparatus further includes a second housing covering the planar light source; a second temperature sensor disposed outside of the first housing and inside of the second housing; a light-source drive circuit including light-source drive section each driving and controlling the light emitting elements belonging to the corresponding light emitting region; a memory section; and a computing section calculating a driving condition of each light-source drive section and correcting the driving condition on the basis of measurement values of the first temperature sensor and the second temperature sensor, and setup information in the memory section."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Planar lighting apparatus and liquid crystal display apparatus","description":"Provided are a planar lighting apparatus, a liquid crystal display apparatus, and a planar light source.
