    摘要: The top surface (41U) of a light guiding plate (41) includes two kinds of regions, i.e., a line grid region (LR) and a scattered grid region (SR). The line grid region (LR) is positioned at a part where light which propagates along a Y direction reaches, on the top surface (41U). The scattered grid region (SR) is positioned at a part where light which propagates in directions deviated from the Y direction reaches, on the top surface (41U).
