Patent number: 7855703Abstract: A liquid crystal display capable of being minimized, in which a backlight assembly has a light source portion for generating light, a liquid crystal display panel receives the light from the backlight assembly to display images. A mold frame for sequentially accepting the backlight assembly and liquid crystal display panel is formed to be gradually thinner as further advancing from a first side of accepting to place the light source portion toward a second side opposing to the first side. Also, a chassis coupled to be opposite to the mold frame for closely fixing the backlight assembly and liquid crystal display panel to the mold frame is formed to be gradually thinner as further advancing from the first side of accepting to place the light source portion toward the second side opposing to the first side. Thus, the liquid crystal display can be slimmed.Type: GrantFiled: July 21, 2000Date of Patent: December 21, 2010Assignee: Samsung Electronics Co., Ltd.Inventors: Jung Tae Kang, Choong Seob Oh, Jin Ho Park, Nam Soo Kang, Jin Hyeok Park, Jong Seon Kim, Soo Han Hur
