Said backlight module comprises a light guide plate, a reflection sheet and a backplane, wherein said reflection sheet is arranged under the light guide plate; said backplane is arranged under the reflection sheet and partially supports the reflection sheet; and said reflection sheet is bent to form one or more supporting ribs for supporting the backplane to prevent the reflection sheet from drooping. The present invention solves the problem that the reflection sheet is affected by heat and then is easy to droop, by bending the reflection sheet of the backlight module to form the one or more supporting ribs for supporting the reflection sheet, and has the advantages of low cost and no negative influence on other components and system structure of the backlight module."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Back light module and liquid crystal display device using the same","description":"The present invention discloses a backlight module and a LCD using the same.
