摘要：
显示装置(12)具有包括多个LED(58)的光源部(60)和覆盖光源部(60)的罩部(38、40)。罩部(38)包括对置部(74)和侧壁部(85)。对置部(74)具有使光源部(60)发出的光直线传播的直线传播部(ST)，侧壁部(85)具有使光源部(60)发出的光散射的第一散射部(SC1)。从光源部(60)照射到直线传播部(ST)的光的一部分没有散射而从罩部(38)向外部射出。照射到直线传播部(ST)的光的其他一部分在对置部(74)内反复反射并且被引导到侧壁部(85)，在第一散射部(SC1)中散射。光源部(60)发出的光之中在罩部(38)的内表面反射的光的一部分照射到侧壁部(85)上，在第一散射部(SC1)中散射。
摘要（英）：

A display device 12 has a light source portion 60 which includes a plurality of LEDs 58, and cover portions 38, 40 which cover the light source portion 60. The cover portion 38 includes an opposed portion 74 and a side wall portion 85. The opposed portion 74 has a straight-through portion ST which allows light emitted from the light source portion 60 to travel straightly, whereas the side wall portion 85 has a first scatter portion SC1 which scatters the light emitted from the light source portion 60. Part of the light thrown from the light source portion 60 to the straight-through portion ST leaves the cover portion 38 to the outside without being scattered. A different part of the light thrown to the straight-through portion ST repeats reflection inside the opposed portion 74, reaches the side wall portion 85, and is scattered in the first scatter portion SC1. Of the light emitted from the light source portion 60, part of the light reflected by an inner surface of the cover portion 38 is thrown to the side wall portion 85, and then scattered in the first scatter portion SC1.
