    Abstract: A display apparatus includes a display panel; and a backlight unit configured to provide light to the display panel. The backlight unit includes: a substrate including a first surface facing the display panel; a light source disposed on the first surface; a driving element disposed on the first surface to drive the light source; a plurality of lines provided on the first surface; and at least one jumper connector disposed on the first surface. Each of the at least one jumper connector corresponds to a first line and a second line of the plurality of lines, such that the jumper connector is disposed in a crossing region of the first surface at which the first line crosses the second line, and the jumper connector electrically connects with the first line and guides the second line to be spaced apart from the first line.
