A backlight unitincludes LED units, a light guide plateand a follow-up mechanism. The light guide platehas light entrance surfacesand a light exit surface. The light entrance surfacesare provided so as to face the respective LED units. The light exit surfaceis provided parallel to an arrangement direction in which the LED unitsand the light entrance surfaceare arranged (i.e., the Y-axis direction) and such that light exits therethrough. The follow-up mechanism is configured to move the LED unitU in the arrangement direction in response to a deformation of the light guide plate. The follow-up mechanism includes a support memberthat supports the LED unitU. The support member is in contact with a surface of the light guide platealong the light entrance surfaceU.
