Problems solved by technology

[0009] Utilizing a display device equipped with such an imaging optical system has the disadvantage of requiring correction
[0010] First, in the case where the display device includes multiple light sources, the image of the information item seen by the user through the front surface may consist of multiple partial images of the information item, which is not satisfactory for the user
[0011] Moreover, the viewing angle for users to obtain clear images is easily limited
More specifically, users located in the peripheral area of ​​the display device cannot clearly view the information, which is restrictive and even dangerous for users driving a vehicle
