Abstract: front page image
(EN)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).
(FR)La surface de dessus (41U) d’une plaque guide de lumière (41) comporte deux types de régions, à savoir une région de grille linéaire (LR) et une région de grille à diffusion (SR). La région de grille linéaire (LR) correspond à une région d’incidence de la lumière se propageant selon une direction Y sur la surface de dessus (41U). La région de grille à diffusion (SR) correspond à une région d’incidence de la lumière se propageant dans des directions s’écartant de la direction Y sur la surface de dessus (41U).
(JA) 導光板(41)の天面(41U)には、2種類の領域である列状格子領域(LR)と散状格子領域(SR)が含まれる。列状格子領域(LR)は、天面(41U)にてY方向に沿って伝播する光の到達部分に位置する。散状格子領域(SR)は、天面(41U)にてY方向から逸脱して伝播する光の到達部分に位置する。
