Electronic device and augmented reality electronic device
An electronic device includes a light adjusting component. The light adjusting component includes a panel, a first quarter wave plate and a second quarter wave plate. The panel includes a first substrate, a second substrate and a medium layer disposed between the first substrate and the second substrate. The first quarter wave plate is disposed on a first side of the panel, wherein the first quarter wave plate has a first retardation amount. The second quarter wave plate is disposed on a second side of the panel opposite to the first side, wherein the second quarter wave plate has a second retardation amount. The first retardation amount is different from the second retardation amount.
