Abstract: A display apparatus includes LEDs disposed behind a display panel; a bottom chassis to accommodate the LEDs; and a reflective member disposed on the bottom chassis. The reflective member includes a reflective inclined portion obliquely formed to face a rear surface of the display panel and including first regions that respectively correspond to LEDs located adjacent to the reflective inclined portion, and second regions each of which is provided between two neighboring first regions. The first regions include light adjusting members, and each of the second regions has a reflective characteristic different from a reflective characteristic of a neighboring first region. Each of the first regions includes a group of light adjusting members which is disposed to correspond to one of the LEDs disposed adjacent to the reflective inclined portion. The two neighboring first regions have more light adjusting members, respectively, than one of the second regions disposed therebetween.

Abstract: A display apparatus includes a display panel, LEDs disposed behind the display panel and spaced from the display panel to emit light toward the display panel, a bottom chassis configured to accommodate the LEDs, and a reflective member disposed inside the bottom chassis and configured to reflect a light portion incident thereon toward the display panel. The reflective member includes a reflective bottom portion corresponding to a front surface of the bottom chassis, and reflective inclined portions obliquely formed to face a rear surface of the display panel and having a plurality of holes thereon. The reflective inclined portions include a first region that corresponds to an LED and a second region that is between two neighboring LEDs, and the first region has a higher hole density than the second region, and the first region is closer to the LED than the second region.

Abstract: A LED module includes a printed circuit board, LEDs which are vertically mounted on the printed circuit board and which emit light onto a side surface, and a contact member which is provided to come into contact with a light guide plate. The printed circuit board may be movably coupled to a bottom chassis. When the light guide plate undergoes thermal expansion, the LED module may move by pressing of the light guide plate acting on the contact member. Accordingly, a gap between the light guide plate and the LEDs may be uniformly maintained even when the light guide plate undergoes thermal expansion or is returned to an original state.
