A structure having reflective glyph plates 431 and 441 disposed inclined in 401 and a protective plate 403 formed of a transparent material to close the opening of the housing 401 was applied.

This structure has an advantage that the display information transmission irradiation area to the driver can be adjusted by the inclination angles of the reflective patterns 431 and 441.

Alternatively, as shown in FIG. 9, the surface may be applied to have a concave-convex shape to cause diffuse reflection on the surface of the reflective pattern plate 451 to enlarge the display pattern.

In addition, as shown in FIG. 10, a white light source 550 that emits white light is used as the light scanning part, and the reflective panel 540 emits light incident in the housing 401 at different angles according to the wavelength. It is formed in a spherical shape but may be formed in a structure having a plurality of flood ball 541 arranged to correspond to the set facial expression pattern.

In this case, light is emitted at different angles for each wavelength through the floodlight ball 541, so that the driver may be able to transmit a minute expression of a different image shape, a frown, and a speed limit display information.

The safety promotion display device 100 described above provides safe smiles or frowns according to the detected speed of the vehicle to be easily transmitted to the driver's field of view through the road surface. It is possible to induce and display the facial expression image even when the road surface is covered by snow, thereby providing facial expression information for guiding safe driving regardless of the road surface condition.

Meanwhile, in the illustrated example, the example in which the faculty promotion display device 100 is installed in the school zone 101 has been described. Of course, it may be installed in various places where safety driving is required, such as a traffic accident multiple area.
