摘要：
The present invention is aimed at solving a problem that a non-uniform luminance and white uneveness which may be caused by contact between a reflecting sheet and a protecting member. A light source side end portion (3a) of a reflecting sheet (3) and a protecting member (5) are located with a spacing (H) between them for preventing contact between them. The spacing (H) for preventing contact between them may be obtained by decreasing a protruding length of the light source side end portion (3a) of the reflecting sheet (3), by displacing a light source (2), or by decreasing diameters of the light source (2) and the protecting member (5).
