A method for producing a display unit, which comprises a case, a panel, a lamp, an intermediate with a positioning portion and a lead wire. The lamp is placed next to the panel, and the lead wire is electrically connected to the lamp to form a conjunctive portion. The conjunctive portion is placed in a mold and integrally covered with the intermediate. The positioning portion of the intermediate is placed next to and abutted against the case while the lamp connected with the lead wires is together disposed on the case. When the lead wire is pulled by an abnormal or abrupt force, the majority of the force can be absorbed by the intermediate pressed on the case, and the lead wire can remain fixed to the lamp.
