PURPOSE: A light emitting diode display device is provided to improve visibility and aesthetics when a light emitting diode is off state. CONSTITUTION: A coupling bar(400) comprises a molding bar(401), an electric wire insertion hole(402), an electric wire connection hole(403), and an electric wire(404). The cross section of the molding bar has a symmetric structure in left and right has light emitting diodes in both sides. The electric wire insertion hole is formed in the molding bar in longitudinal direction. The electric wire is inserted into the wire insert hole. The electric wire insertion hole opens in the combination direction of the light emitting diode unit and exposes one side of the electric wire. The electric wire insertion hole is combined with the terminal pin of a light emitting diode unit. A pair of electric wire insertion holes and electric wires are formed in both sides and are connected to the positive electrode and a negative electrode of the light emitting diode. |
