    a reflection plate that is provided on a side of an opposite surface of the light-guiding plate that is opposite to the light emitting surface, and reflects light, whereinthe reflection plate includes a bent portion formed by bending an end portion of the reflection plate so that the bent portion surrounds the light source while being in close contact with the mounting surface of the light source substrate;

    the reflection plate includes a principal surface that is opposite to the opposite surface of the light-guiding plate;

    the bent portion includes;

    a lower surface that is formed continuously to the principal surface and located below the light source;

    a back surface that is formed continuously to the lower surface and in close contact with the mounting surface of the light source substrate on the back surface side of the light source; and

    an upper surface that is formed continuously to the back surface and located above the light source; and

    the back surface includes a through hole arranged to receive the light source, such that the back surface is arranged between the light source and the light source substrate.
