Abstract:
1. An illuminating device, comprising: a case member having: a bottom portion; and a plurality of side portions formed to stand up from a periphery of the bottom portion, the case member including a housing space formed as a space surrounded by the plurality of side portions and located at a side of an upper surface of the bottom portion; a light guide plate placed in the housing space, the light guide plate at least including: a light incident surface which is a predetermined side-end surface; and a light exit surface that is a surface perpendicular to the light incident surface and facing an illuminated body, and the light guide plate being placed above the upper surface of the bottom portion of the case member; a light emitting diode device placed in the housing space, the light emitting diode device being arranged such that a light emitting surface thereof faces the light incident surface of the light guide plate, and the light emitting diode device being mounted on a predetermined first side portion of the plurality of side portions of the case member; a power supply board arranged outside the housing space; a connection member electrically connecting the light emitting diode device to the power supply board; and a reflection sheet arranged between the bottom portion of the case member and the light guide plate; wherein the connection member is extended, from a side where the light emitting diode device is located, along a second side portion of the case member that is different from the first side portion, such that a connection terminal of the connection member that is connected to the power supply board is far away from the light emitting diode device; the connection terminal of the connection member is drawn out from an inside to an outside of the housing space through a drawing-out hole formed in the case member, with the connection member extended, from the side where the light emitting diode device is located, along the second side portion of the case member; the drawing-out hole is closed in a state in which the connection terminal of the connection member is drawn out through the drawing-out hole; and the drawing-out hole is formed in the bottom portion of the case member and closed with the reflection sheet.
