A gap is provided between the light guide plates, and the position of the entrance edge is fixed among the edges of the light guide plate. If the light guide plates are expanded in accordance with a change in temperature or humidity, the entrance edge do not move while the light guide plates are expanded so as to approach each other. Since the light guide plate does not hit the light source and the amount of expansion of the light guide plates is absorbed into the gap, the light source may be arranged as close as possible to the entrance edge of the light guide plate in the lighting device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Lighting device and display apparatus","description":"A lighting device used as a backlight of a display apparatus includes multiple light guide plates, and a light source located near an entrance edge of each light guide plate to emit light.
