Patent number: 11143915Abstract: A lighting device includes light sources arranged in a row in an arrangement direction, alight guide plate disposed to cover the light sources and including a plate surface facing the light sources and an opposite plate surface opposite from the plate surface, and a light diffusion portion. A portion of the plate surface is a light entering surface and the opposite plate surface is a light exit surface. The light diffusion portion extends in the arrangement direction of the light sources and on the light exit surface such that a portion of the light diffusion portion overlaps the light sources. The light diffusion portion applies a diffusion effect to light that is within the light guide plate so as to travel in a direction crossing the arrangement direction and to be away from the light sources seen from a normal direction of the light exit surface.Type: GrantFiled: September 11, 2020Date of Patent: October 12, 2021Assignee: SHARP KABUSHIKI KAISHAInventors: Shugo Yagi, Takeshi Masuda, Satoshi Tsubooka, Yuuichi Kanbayashi
