BACKLIGHT UNIT, LIGHTING DEVICE AND DISPLAY APPARATUS

摘要

The present invention relates to a backlight unit, a lighting device, and a display device. The backlight unit includes a light guide plate; a light emitting module which is installed along the side of the light guide plate and can emit light to the light guide plate; a support frame which allows the light emitting module to move back and forth to receive the thermal expansion deformation of the light guide plate; and an elastic member which is installed between the light emitting module and the support frame and has resilience for pressurizing the light emitting module toward the light guide plate. The elastic member may include a first fixing part fixed to a side of the light emitting module; a first leg part which protrudes from the first fixing part to a first direction facing the inner wall of the support frame; and a second leg part which is made of an elastic material and protrudes from the first fixing part to a second direction facing the inner wall of the support frame.
