<p>An illumination device (12) is provided with: a housing member (22) that has a bottom plate (22a), a side wall (22b), and a pair of protrusions (22c); a light guide plate (26) having a pair of first end surfaces (26d) and a pair of second end surfaces (26b) that extend in a direction intersecting the first end surfaces (26d), having a pair of concavities (26e) at the respective first end surfaces (26d), and being disposed in the housing member (22) in a manner so that the rear surface (26c) thereof faces the bottom plate (22a) and the concavities (26e) respectively fit the protrusions (22c); a light source unit (2) having a light source (24) and being disposed in the housing member (22) in a manner so that the light source (24) faces at least the second end surfaces (26b) of the light guide plate (26); and a frame (27) having a frame-shaped overhang plate (27a), which covers the outer periphery (W) of the plate surface (26a) of the light guide plate (26), and a restraining section (27c) that protrudes downwards from the overhang plate (27a) in a manner so as to selectively restrain the perimeter (S0) of the concavity (26e) of the plate surface (26a) of the light guide plate (26).</p> |
