Display device

Disclosed is a display device. The display device of the present disclosure may include: a display panel; a frame which is located in a rear of the display panel and to which the display panel is coupled; a substrate which is located between the display panel and the frame and coupled to the frame; and a plurality of light sources which are mounted on the substrate and spaced apart from each other, wherein the substrate may include: an elongated first plate; and a plurality of second plates which extend from the first plate in a direction intersecting with a length direction of the first plate, and are spaced apart from each other in the length direction of the first plate.

According to one or more embodiments, a display device may include: a display panel; a frame located behind the display panel, and to which the display panel is coupled; a substrate located between the display panel and the frame, fixed to the frame, and extending along a length direction; a plurality of light sources successively mounted on the substrate along the length direction of the substrate; and a lens extending along the length direction of the substrate to cover the plurality of light sources, and fixed to the substrate, wherein the lens may include: a first dome portion which forms an upper surface, and is convex; a second dome portion which forms an upper surface, and is adjacent to the first dome portion; a receiving portion recessed from a lower surface of the lens toward the upper surface, and in which the plurality of light sources are located.

A display device is disclosed. The display device includes: a display panel; a frame disposed at a rear of the display panel; a light source disposed between the display panel and the frame, and configured to provide light to the display panel; a guide panel disposed adjacent to an edge of the display panel and coupled to the frame, and configured to support the display panel; and a front sheet including a light transmitting portion covering a front surface of the display panel, and a light shielding portion extending from the light transmitting portion and covering the guide panel, wherein the guide panel includes: an inner part disposed between the frame and the display panel and configured to support a rear surface of the display panel adjacent to the edge of the display panel; and an outer part disposed toward an outer side of the frame and configured to cover a side surface of the edge of the display panel.

Provided are a backlight unit and a display apparatus including the same. The backlight unit includes a bottom cover, a substrate, light sources, light guide panels, at least one reflective member, and an optical sheet. The substrate is in the bottom cover. The light sources are on the substrate to emit light at an orientation angle from a first direction. The light guide panels include a light incident part having a light incident surface to which light is incident in the first direction from the light sources, and a light emitting part that emits the incident light in a second direction crossing the first direction and has a side connected to the light incident part. The reflective member includes a reflective region overlapping the light guide panel and an extension region that does not overlap the light guide panel. The optical sheet is above the light guide panel.

Optical assembly, backlight unit including the same, and display apparatus including the backlight unit

Provided are a backlight unit and a display apparatus including the backlight unit. The backlight unit includes light sources, light guide plates, and a bottom cover. The light sources emit light in a first direction. The light guide plates have first sides spaced a predetermined distance in the first direction from each other and facing each other. The light guide plates at least partially overlap each other. The light emitted from the light source is incident in the first direction to the first side and emitted in a second direction crossing the first direction. The bottom cover receives the light source and the light guide plate and includes a side border facing a second side of the light guide plate spaced apart from the first side of the light guide plate by an extension length of the light guide plate in the first direction.
