A conventional road traffic display device is composed of a landmark installed on a ground or a road structure and a traffic sign installed on the top of the landmark. The traffic sign is displayed on the surface by a method such as printing, There is enough identification in the weather or week.

The traffic sign is usually installed on a metal plate in a reflective manner. The metal plate is formed with a coating layer on which a base color coating layer, for example, green, blue or the like is applied, and a guide mark, And when a vehicle lighting is projected on the traffic sign at night according to guide display, the guide display made of a high-luminance reflection sheet scatters light emitted from the vehicle, Can be easily recognized

However, in the case of a bad weather condition such as a fog in a rainy weather, the discrimination power was considerably lowered, and the function of the guide plate could not be performed properly, which resulted in a traffic accident.

In addition, since characters or graphics displayed on the traffic sign can not be modified or changed as needed, traffic information, road information, and the like can not be actively provided according to road conditions or weather conditions.

Korean Utility Model Registration No. 20-0400256, Korean Registered Utility Model Registration No. 20-0292860 discloses a device having a structure in which an LED module is embedded in a traffic sign so as to reliably perform a road traffic display function However, there is a problem that it is difficult to completely solve the above-mentioned problems while reducing work productivity and construction cost due to complicated installation structure and wiring structure.
