LIGHT GUIDE BODY AND LIGHT-EMITTING DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress occurence of a bright line in a region in which different light-emitting regions are overlapped with each other.SOLUTION: A light-emitting device (1) includes a light guide plate (4) including: a first light-emitting region (A) corresponding to a first reflection region for reflecting light (L1); and a second light-emitting region (B) corresponding to a second reflection region for reflecting light (L2). In the light guide plate (4), a reflection amount of the first reflection region in the region in which the first reflection region and the second reflection region are overlapped attenuates gradually as approaching a boundary line (A') of the first reflection region.SELECTED DRAWING: Figure 2
