Abstract: An electronic device is provided. The electronic device includes a first privacy panel and a second privacy panel disposed on the first privacy panel. The first privacy panel has a first alignment layer and a second alignment layer opposite each other. The second privacy panel has a third alignment layer and a fourth alignment layer opposite each other. The alignment axes of the first alignment layer, the second alignment layer, the third alignment layer and the fourth alignment layer are parallel. The angle between the alignment direction of the first alignment layer and the alignment direction of the third alignment layer is in a range from 160 to 200 degrees. The angle between the alignment direction of the second alignment layer and the alignment direction of the fourth alignment layer is in a range from 160 to 200 degrees.

Abstract: An electronic device is provided. The electronic device includes a light-emitting layer, a light-controlling layer, a retardation layer, and a viewing angle switching structure. The light-controlling layer is disposed on the light-emitting layer. The light-controlling layer is disposed between the light-emitting layer and the retardation layer. The viewing angle switching structure includes a first linear polarizer, a liquid-crystal layer, and a second linear polarizer. The retardation layer is disposed between the light-controlling layer and the first linear polarizer. The liquid-crystal layer is disposed between the first linear polarizer and the second linear polarizer. The first linear polarizer has a first transmission direction, the second linear polarizer has a second transmission direction, and the first transmission direction and the second transmission direction are parallel.

Abstract: An electronic device is provided. The electronic device includes a display panel, a light-controlling layer, a retardation layer, and a first linear polarizer. The light-controlling layer is disposed between the display panel and the retardation layer. The retardation layer is disposed between the light-controlling layer and the first linear polarizer. A first transmission direction of the first linear polarizer is different from a second transmission direction of at least a portion of an incident light. The incident light passes through the retardation layer so as to enter the first linear polarizer.

Abstract: The disclosure provides an electronic device including a viewing angle control structure. The viewing angle control structure includes a first substrate, a second substrate disposed opposite to the first substrate, an adjustable dielectric layer disposed between the first substrate and the second substrate, a first alignment layer disposed between the first substrate and the adjustable dielectric layer, and a second alignment layer disposed between the second substrate and the adjustable dielectric layer. One of the first alignment layer and the second alignment layer is in a horizontal alignment and the other of the first alignment layer and the second alignment layer is in a vertical alignment.
