The light guide plate includes a light guide plate body and a plurality of microreliefs. The light guide plate body has a light-emitting surface and a reflecting surface. The microreliefs are disposed on the reflecting surface. Each of the microreliefs has an outer surface and a base area. The outer surface is a curved surface, and the base area contacts the reflecting surface. A ratio of the totally height of each of the microreliefs to the diameter of the base area of each of the microreliefs is between 1/7 and ¼. As a result, the light guide plate has higher light extraction efficiency."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light guide plate and back light module having the same","description":"The present invention relates to a light guide plate and back light module having the same.
