PROBLEM TO BE SOLVED: To obtain a direction display by which a distinction is made easy and with which a misconception is hard to generate by a method, wherein light emitting states of a plurality of multicolor light emitting diodes are controlled, according to a plurality of direction display signals which are input from the outside. SOLUTION: A two-color light emitting diode LED1 to a two-color light emitting diode LED36, which are arranged in a direction display console, are housed in one package in such a way that their respective red (or green) light emitting parts R (or G) are brought close. Terminals on the side of cathodes in the respective red (or green) light emitting parts R (or G) inside the respective LEDs are connected to a selector Sr (or Sg) for turning-on. An input terminal I1 to an input terminal I3 are used to input three kinds of direction indicating signals 1 to 3. Then, the direction indicating signal 1 (or 2) is supplied to the red (or green) selector Sr (or Sg). A current flows to both light emitting parts R, G from a DC power supply circuit Vcc. Respective red colors and green colors are turned on. In the direction indicating signal 3, both light emitting parts R, G emit light, and an orange color which additively color-mixes both parts is recognized visually. Thereby, the arrival directions (or angles) of radio waves indicated by the direction indicating signals 1 to 3 are displayed in a red turning-on position, a green turning-on position and an orange turning-on position.
