Each light guide plate has a light entrance surface and a light exit surface. The light entrance surface faces the LED. Light from the LED enters the light entrance surface. The light exit surface is parallel to a Y-axis direction. The light guide plates are arranged in lines along the Y-axis direction so as to overlap one another in a Z-axis direction, and are fixed to the LED boards with the clips. A first light guide plate is arranged on a rear-surface side with respect to a second light guide plate, which is arranged on a front-surface side. The locking structures are configured to restrict a relative movement of the second light guide plate in the X-axis direction and the Y-axis direction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Lighting device, display device and television receiver","description":"A backlight unit includes LEDs, light guide plates, LED boards, clips and locking structures.
