PURPOSE: A price display device is provided to change price information of a product through wired or wireless communications and to display the changed price information of the product after changing the price information. CONSTITUTION: An EL(Electroluminescence)(130) displays a predetermined pattern by selective light emission. The EL device formed on the upper side of a substrate(110) includes multiple EL pixels. An RFID(Radio Frequency Identification) antenna(120) is formed on the substrate. An RFID chip(210) is electrically connected with the RFID antenna. The RFID chip stores data which is transceived through the RFID antenna. According to the data, an EL driving unit(220) selects/drives pixels to be emitted among the multiple EL pixels.
