1. An electronic device, comprising:
a display panel, wherein the display panel comprises a surface, the surface is constituted by a first direction and a second direction, and the first direction and the second direction are perpendicular,
wherein the display panel comprises a light-emitting layer;
a light-controlling layer disposed on the surface of the display panel;
a retardation layer disposed on the surface of the display panel, wherein the light-controlling layer is disposed between the display panel and the retardation layer; and
a viewing angle switching structure disposed on the surface of the display panel, wherein the viewing angle switching structure comprises:
a first linear polarizer, wherein the retardation layer is disposed between the light-controlling layer and the first linear polarizer;
a liquid-crystal unit; and
a second linear polarizer, wherein the liquid-crystal unit is disposed between the first linear polarizer and the second linear polarizer,
wherein a first light reflected by the display panel passes through the light-controlling layer and the retardation layer to form a second light, and the second light enters to the first linear polarizer along a third direction away from the display panel, and
wherein the first linear polarizer has a first transmission direction that is the same as the first direction, the second light has a second transmission direction that is the same as the second direction, and the third direction is perpendicular to the first direction and the second direction.
