The light guide plate includes protrusions and recesses formed on one of the front surface and a rear surface on an opposite side of the front surface. The protrusions and recesses are formed of a shape in which first mountain-range shapes each including a first ridge continuing along a first direction, which is a direction toward the inside from the end surface, and second mountain-range shapes each including a second ridge continuing along a second direction intersecting with the first direction are combined. Each first mountain-range shape includes a pair of first side surfaces on both sides of the first ridge. Each second mountain-range shape includes a pair of second side surfaces on both sides of the second ridge."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Liquid crystal display device using light guide plate","description":"A light guide plate is for reflecting incident light from an end surface thereof in an inside to obtain surface emission from a front surface thereof.
