Abstract
A time display device which utilizes light beams to display time is disclosed. The time display device at least comprises a timetable panel, an illuminant module, a counter unit, and a control unit. When the counter unit sends a counting result to the control unit, the control unit controls the illuminant module to respectively emit three color light beams projected on the timetable panel through the shielding of at least one shielding structure to form three color image areas with different distances to represent a second, a minute and a hour corresponding to the counting result.
