Abstract
A backlight module comprises a back plate, a reflective sheet arranged on the back plate and forming a plurality of openings, a plurality of light-emitting elements located in the plurality of openings, at least one optical element arranged on the reflective sheet, and at least a supporting element configured between the back plate and the reflective sheet. The supporting element can move along with the reflective sheet. The supporting element has a base portion and a supporting portion extending from the base portion towards the optical element. The base portion of the supporting element is located between the back plate and the reflective sheet. The supporting portion of the supporting element passes through the reflective sheet to support the optical element. The supporting element is not a fixed design and can move along with the reflective sheet. Therefore, other plates under the reflective sheet do not require openings, which can improve assembly convenience and effectively reduce the mechanism interference caused by the expansion and contraction of the reflective sheet. The invention also provides a display device including the backlight module.
