The sidewall is extended from the bottom plate to define a receiving space. The grounding unit is integrally formed with the bottom plate. The grounding unit includes a grounding member that grounds a circuit board received in the receiving space. The circuit board includes a grounding electrode and the grounding member corresponds to the grounding electrode. The grounding member is formed on a rear surface of the bottom plate. The grounding member may include a protrusion or a projected portion having an elastic structure. ## Claims ### Claim 1 A backlight assembly, comprising: a light source generating light; a single unitary indivisible bottom chassis configured to receive the light source, the bottom chassis being electrically conductive and comprising: a bottom plate comprising a front surface facing the light source, and a rear surface opposite to the front surface; a sidewall extending from the bottom plate to define a receiving space configured to receive the light source; and a grounding member on the rear surface of the bottom plate, the grounding member integrally formed with the bottom plate; an upper frame coupled to the bottom chassis; a circuit board disposed on the rear surface of the bottom plate; and an insulation layer disposed between the circuit board and the rear surface of the bottom plate, wherein the insulation layer defines an opening exposing the circuit board and a portion of the rear surface of the bottom plate, and through which the grounding member protrudes, and the grounding member comprises: an extension portion which extends toward the circuit board in a first direction; and a contact portion which further extends from the extension portion in a second direction different from the first direction, and contacts the circuit board. ### Claim 2 (depends on 1) The backlight assembly of claim 1, wherein the circuit board comprises a grounding electrode; and the contact portion of the grounding member contacts the grounding electrode. ### Claim 3 (depends on 2) The backlight assembly of claim 2, wherein the extension portion is extended obliquely toward the circuit board and the contact portion is extended substantially parallel with the circuit board. ### Claim 4 (depends on 3) The backlight assembly of claim 3, wherein the contact portion and the grounding electrode contact with each other by face-to-face contact. ### Claim 5 (depends on 1) The backlight assembly of claim 1, wherein an opening is formed on an area of the bottom plate corresponding to the grounding member. ### Claim 6 A display device comprising: a display panel displaying an image; a circuit board providing the display panel with a driving signal; and a backlight assembly, comprising: a light source generating light; a single unitary indivisible bottom chassis configured to receive the light source, the bottom chassis being electrically conductive and comprising: a bottom plate comprising a front surface facing the light source, and a rear surface opposite to the front surface, the circuit board disposed on the rear surface of the bottom plate; and a sidewall extending from the bottom plate to define a receiving space configured to receive the light source; and a grounding member on the rear surface of the bottom plate, the grounding member integrally formed with the bottom plate; an upper frame coupled to the bottom chassis configured to receive the display panel; and an insulation layer disposed between the circuit board and the rear surface of the bottom plate, wherein the insulation layer defines an opening exposing the circuit board and a portion of the rear surface of the bottom plate, and through which the grounding member protrudes, and the grounding member comprises: an extension portion which extends toward the circuit board in a first direction; and a contact portion which further extends from the extension portion in a second direction different from the first direction, and contacts the circuit board. ### Claim 7 (depends on 6) The display device of claim 6, wherein the circuit board comprises a grounding electrode; and the contact portion of the grounding member contacts the grounding electrode. ### Claim 8 (depends on 7) The display device of claim 7, wherein the extension portion is extended obliquely toward the circuit board and the contact portion is extended substantially parallel with the circuit board. ### Claim 9 (depends on 8) The display device of claim 8, wherein the contact portion and the grounding electrode contact with each other by face-to-face contact. ### Claim 10 (depends on 6) The display device of claim 6, wherein an opening is formed on an area of the bottom plate corresponding to the grounding member.
