Since the plurality of display elements 211 are connected in series, the voltage of the entire display assembly 21 increases, and the current flowing through the display elements 211 decreases, so that the amount of heat generated by the display elements 211 decreases, and the power consumption of the entire display assembly 21 decreases. Meanwhile, since the power consumption of the display element 21 is reduced, the size of the display element 21 can be properly reduced, and accordingly, the optimum current density is smaller, the display element 21 can more easily achieve its optimum current density based on the above-described structure. Preferably, the display member 211 is a Mini-LED light emitting element, a Micro-LED light emitting element.
