1. A display device having a first region adjacent to a transflective object in a vehicle, comprising:
a first light emitting element disposed in the first region;
a light controlling means disposed on a route that a first light and a second light emitted from the first light emitting element propagate, through which the first light is controlled to propagate out of the display device at a first angle ranged from 30 degrees to 45 degrees and toward the transflective object and the second light is controlled to propagate out of the display device at a second angle ranged from 0 degrees to 5 degrees;
a second region adjacent to another transflective object opposite to the transflective object in the vehicle; and
a second light emitting element disposed in the second region, the light controlling means disposed on a route that a third light emitted from the second light emitting element propagates, through which the third light is controlled to propagate out of the display device at a third angle ranged from 55 degrees to 70 degrees and toward the another transflective object,
wherein a first ratio of a light intensity of the first light to that of the second light is less than or equal to 14%,
wherein a second ratio of a light intensity of the third light to that of the second light is less than or equal to 23%.
