Provided is a high-quality sign board including an organic light emitting device (OLED) which can be easily adapted to various designs applied by users to the sign board. The sign board includes a substrate, a plurality of first conductive lines disposed on the substrate, a plurality of pixel electrodes electrically connected with the first conductive lines, an intermediate layer comprising a light emitting layer disposed on the pixel electrodes, and a face electrode disposed on the intermediate layer. In another embodiment, the sign board further includes a plurality of second conductive lines, each of which connects at least two of the first conductive lines to each other. In still another embodiment, the plurality of pixel electrodes includes a plurality of first pixel electrodes electrically connected with the first conductive lines, and a plurality of second pixel electrodes that are not electrically connected with the first conductive lines. |
