Patent number: 9869809Abstract: Sufficiently sharp directivity can be secured with a simple configuration in a configuration that improves the efficiency of utilizing the light exiting from a primary light source using a reflective polarizing plate. A backlight unit (2) supplies light exiting from an exit surface of a light guide plate (12) to a liquid-crystal display panel (3) via a reflective polarizing plate (16) after correcting directivity of the exiting light using a prism sheet (14) having a downwardly convex shape. A ¼-wavelength plate (15) is provided between the prism sheet (14) and the reflective polarizing plate (16), between the prism sheet (14) and the light guide plate, or between the light guide plate and a reflective sheet disposed on a surface of the light guide plate opposite to the prism sheet (14).Type: GrantFiled: March 10, 2015Date of Patent: January 16, 2018Assignee: Dai Nippon Printing Co., Ltd.Inventors: Keiji Kashima, Yasuki Suzuura, Hiroshi Yamamoto, Takashi Kuroda
