Patent ID: 7859613

Claim:
A liquid crystal display device comprising: a liquid crystal display panel; a light guide plate; a light source providing light to a rear surface of the liquid crystal display panel comprising: a light source body in the shape of a cylinder having a light source electrode disposed at each of two ends of the light source body, wherein the light source body is disposed at a lateral side of the light guide plate; an inverter providing power for the light source; a light source wire connected between the inverter and the light source electrodes, and having a connecting terminal with a ring shaped portion at one end of the light source wire; an electric conduction terminal having an electrode inserting cavity for accommodating the light source electrode at a first end and a coupling cavity for coupling with a coupling means passing through the connecting terminal ring-shaped portion at second end opposite the first end, so that the electric conduction terminal connects between the light source electrode at a first end and the light source wire with the connecting terminal at the second end; a light source reflector formed along the light source body and covered a part of a circumference of the light source body, wherein the light source reflector has at least one first coupling part dent-shaped on an inside at the both ends of the light source reflector; and a coupling member having a electric conduction terminal accommodating hole exposing the electrode inserting cavity and the coupling cavity of the electric conduction terminal and coupling to the electric conduction terminal, wherein the coupling member is formed of an insulating material and wherein the coupling member comprises an accommodating part inserted into the light source reflector, a second coupling part provided on the outside of the accommodating part at the one end and preventing the coupling member form being separated form the light source reflector through coupling with the first coupling part, and a flange part provided on the other end of the accommodating part opposite the second coupling part and supported by an end of the light source reflector when the accommodating part is inserted into the light source reflector.
