Abstract:
A brightness distribution of light emitted from one specific light source and outputted from the light outputting part of a light-guide part has a characteristic of having a mountain-shaped distribution increasing from a position of the specific light source, then reaching a maximum value, and then decreasing with distance from a specific light source, and a light source adjacent to the specific light source is disposed at a position where a brightness distribution decreases from the maximum value of the brightness distribution.
