Abstract
The present invention relates to a luminous element, and more particularly, to a luminous element for a backlight unit with a plurality of luminous chips mounted on a substrate. The present invention provides a luminous element for a backlight unit, in which luminous chips are arranged on a substrate so that the manufacturing process and cost can be reduced and the size of a substrate is minimized when manufacturing the luminous element, thereby minimizing the size of a backlight unit. Further, the present invention provides a luminous element for a backlight unit, in which luminance uniformity can be increased by optimizing the viewing angle of the luminous element.
