A plurality of light-emitting diodes are connected in series to elevate the working voltage. A plurality of said series connection are connected in parallel to maintain display even upon a disconnection accident. The total number of light-emitting diodes provides a bright and failure-safe colored light display at a low power consumption. The conventional colored-light-emitting display can be easily substituted by the novel light-emitting diode display to reduce the power consumption and elongate the service lifetime.
