Abstract
Official abstract text for this publication.
Provided is an illuminating device capable of preventing a light guide plate from being shaved because of contact with a fixation member on a back face side of an end portion of the plate. The illuminating device includes alight guide plate ( 11 ), a chassis ( 14 ) housing the plate and including a bottom plate ( 14 a ), and a light source holding member ( 15 ) fixed to the bottom plate by a fixation screw ( 16 ) and holding a light source ( 21 ) close to a light entrance face ( 11 a ) of the light guide plate, and further includes a concave portion 12 preventing contact between a screw head ( 16 a ) of the screw and the light guide plate and disposed on a back face of an end portion ( 11 d ) of the light guide plate at a position where the head is to be disposed if the screw is disposed on a side of the back face.
