PURPOSE: An OLED traffic signal is provided to improve a visibility and simplify a lighting structure by clearly recognizing a color in a refracted angle or an adjacent location and using a cardboard type light source. CONSTITUTION: An OLED traffic signal is manufactured by using an OLED surface light source. The OLED traffic signal is composed of the luminous body of a thin cardboard type. The structure of the OLED traffic signal is very simple and lighting. The OLED traffic signal displays a color through the surface light source. One OLED traffic signal indicates signals from both bidirectional positions. The OLED traffic signal simultaneously indicates the signal of both sides by using two OLED surface light source panels(111,113) of the cardboard type. The opaque diaphragm(112) secluding the light is installed between the OLED surface light source panels.
