Abstract: A display device comprising: a light source plate behind a liquid crystal panel to provide light to the liquid crystal panel. The light source plate comprises: a printed circuit board including a power wiring layer and a photo solder resist (PSR) layer; a plurality of LED chips mountable directly on the printed circuit board; and a plurality of molding parts formed of a molding material comprising a material having thixotropy to respectively surround the plurality of LED chips . A reflective sheet includes a plurality of openings formed to correspond to positions of the plurality of molding parts so that while the reflective sheet is between the liquid crystal panel and the light source plate, the plurality of molding parts are respectively positionable inside the plurality of openings with the plurality of molding members spaced apart from an inner circumferential surfaces of each of the plurality of openings.
