Abstract
A backlight unitincludes a light guide plate, first LEDsA, second LEDsB, first support members, and second support members. The first LEDsA are opposed to a first light entrance surfaceA that is a first edge surfaceEof the light guide plate. The second LEDsB are opposed to a second light entrance surfaceB that is a second edge surfaceEof the light guide plate. The second LEDsB are arranged to be away from the second light entrance surfaceB with a distance B relatively greater than a distance A between the first LEDsA and the first light entrance surfaceA. The first support membersare in contact with the first edge surfaceEof the light guide plateto support the light guide platefrom a first LEDA side. The second support membersare arranged on a same side as the second LEDsB with respect to the light guide plateto be away from the light guide plate. The second support membersare to be in contact with the second edge surfaceEaccording to thermal expansion of the light guide plateto support the light guide platefrom a second light source side. The second support membersare made of an elastic material softer than a material of the first support members
