PURPOSE: A bulb display is provided to have conductive fluid and a light emitting diode, thereby functioning as a lamp. CONSTITUTION: An electrode comprises a spiral electrode(21) and a contact electrode(22). Conductive fluid and a light emitting diode(100) are placed in the bulb. Voltages applied to the spiral electrode and the contact electrode are applied to an internal electrode. The spiral electrode and the contact electrode include internal electrodes(23,24). The spiral electrode and the contact electrode are installed in the body(20) of the bulb. An AC voltage is applied to the light emitting diode. |
