Kind Code:
A1
Abstract:
[Problem] To provide a light guide plate assembly, a light guide plate device, and a light guide plate device with a frame, configured so as to efficiently guide light from a light source into a light guide plate using a simple structure, such that the light guide plate adequately emits light even when thin. [Solution] A light guide plate assembly (6) is provided with: a light guide plate (10) in which light from a light source (20) is introduced from one end face (18) and is emitted from one surface (16); and a cover (30) for sealing the one end face (18), said cover (30) being formed so as to cover the light source (20) and the one end face (18) in cross-sectional view in the long direction, and said cover (30) having a reflective surface (32) for reflecting light that is emitted from the light source (20) but does not impinge on the end face (18). The light reflected by the reflective surface (32) is also incident from the surfaces (14) (16) on the front and back of the light guide plate (10).
