Abstract: A display device including a display panel; a frame at a rear of the display panel; a first substrate at a front surface of the frame, the first substrate elongated in a direction along a first side of the frame; a plurality of first light sources disposed on the first substrate at predetermined intervals in the direction along the first side of the frame; and a first protrusion and a second protrusion between the first substrate and the frame, the first protrusion positioned at an end of the first substrate adjacent to a foremost light source in the first substrate, and the second protrusion positioned at an end of the first substrate adjacent to a rearmost light source in the first substrate, the first protrusion and the second protrusion being inclined. Further, the first protrusion and the second protrusion are inclined so that a height of the first protrusion close to a second side of the frame connected to the first side of the frame is greater than a height of the first protrusion far away from the second side of the frame and a height of the second protrusion close to a third side of the frame connected to the first side opposite the second side of the frame is greater than a height of the second protrusion far away from the third side of the frame.

Abstract: A display device is provided. The display device includes: a substrate; and at least one light assembly separately located on the substrate, wherein the light assembly includes: a light source; and a lens configured to shield an upper surface and a side surface of the light source, wherein the lens includes: a refraction portion separately located on the upper surface of the light source; and a reflection portion separately located at the side surface of the light source. Thereby, the lens includes a reflection portion located at a side surface of the light source, thereby improving light efficiency of a backlight unit.
