Patent number: 10401679Abstract: The display apparatus reflects the light emitted from the light source to a display panel using a reflective member without a member such as a light guide plate. The reflective member is configured so that the light emitted from the light source can be provided uniformly and introduced uniformly to the display panel. Even if a board with the light source disposed at a side of the reflective member, the light emitted from the light source can be radiated substantially uniformly to the entire area of the display panel by the reflective surface of the reflective member.Type: GrantFiled: March 9, 2017Date of Patent: September 3, 2019Assignee: Samsung Electronics Co., Ltd.Inventors: Yong Dok Cha, Jong Bin Kim, Jeong Shan Na, Young Chol Lee, Jae Hak Cho, Jean Hur
