摘要： A light emitting unit may include a housing having a bottom portion parallel to an xz plane and an opened top opposite to the bottom portion, a light emitting chip on the bottom portion and generating light, and a lens which overlaps the opened top of the housing. The lens may have a convex structure with respect to the xz plane when viewed from a cross section parallel to an xy plane and a concave structure with respect to the xz plane when viewed from a cross section parallel to a yz plane.

摘要： A display device includes a display panel which displays an image, a backlight unit which supplies the display panel with light, an upper cover, and a lower cover. The upper and lower covers accommodate the display panel and the backlight unit. The backlight unit includes light guide plates spaced apart from each other, a light source part, an optical member and an optical diffusion member overlapping a space between the light guide plates. The optical diffusion member includes a diffusing part and a supporting part. The diffusing part faces the optical member, overlaps the space between the light guide plates, and diffuses light emitted from the light source part toward the optical member through the space between the light guide plates. The supporting part protrudes from a surface of the diffusing part which is opposite to the optical member, and is in a space between the light sources.

摘要： A light emitting module includes a light source, a printed circuit board, and a connector part. The printed circuit board includes a wiring layer having a wiring electrically connected to the light source, a heat dissipation layer formed under the wiring layer, and a through hole passing through the wiring layer and the heat dissipation layer. The connector part is disposed in the through hole and is electrically connected to the wiring for transmitting a power through the wiring to the light source. The heat dissipation layer may effectively dissipate the heat generated from the light source. A height of a protrusion of the connector part protruding from an upper surface of the printed circuit board may be minimized, such that a dark area caused by the connector part may be minimized, and display quality of a display apparatus including the light emitting module may be optimized.

The upper and lower covers accommodate the display panel and the backlight unit. The backlight unit includes light guide plates spaced apart from each other, a light source part, an optical member and an optical diffusion member overlapping a space between the light guide plates. The optical diffusion member includes a diffusing part and a supporting part. The diffusing part faces the optical member, overlaps the space between the light guide plates, and diffuses light emitted from the light source part toward the optical member through the space between the light guide plates. The supporting part protrudes from a surface of the diffusing part which is opposite to the optical member, and is in a space between the light sources.
