Abstract: A durable flexible circuit board for a transparent display board is connected between a driver board provided with at least one of a power supply and a controller and a transparent plate provided with a plurality of light emitting elements. The flexible circuit board includes an electrode bonding portion provided with a plurality of signal connection terminals for transferring control signals, at least one power connection terminal for transferring electric power, and at least one dummy terminal disposed outside the signal connection terminal or the power connection terminal disposed at the outermost side. The dummy terminal resists vibration and pressure applied to the signal connection terminal or the power connection terminal disposed at the outermost side. The signal connection terminal and the power connection terminal are integrated in the flexible circuit board.
