The light guide plate 16 includes a positioning projection portion 160 that is fitted to the recess portion 134b. The positioning projection portion 160 projects outwardly from a side edge surface 16e of the light guide plate 16. The positioning projection portion 160 has a projection, and among rays of light emitted from an end light source 17X included in the light source row 170 and entering the light guide plate through a light entrance surface 16b, narrow-angle light L2 directed outward at an angle α (a critical angle θc) with respect to an optical axis L1 enters the projection. The positioning projection portion 160 includes a first edge surface 161 and a second edge surface 162. The first edge surface 161 is parallel to a side edge surface 16e and the narrow-angle light L2 reaches the first edge surface 161. The second edge surface 162 is between the side edge surface 16e and the first end surface 161 and is inclined such that an external angle β between the first edge surface 161 and the second edge surface 162 is equal to or smaller than the critical angle θc."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Display device and television device","description":"A display device 10 includes a display panel 11, a light source row 170, a light guide plate 16, a chassis 14 and a recess portion 134b that is fitted the chassis 14.
