Abstract
A head-mounted display device and a zoomable optical device thereof is disclosed. The zoomable optical device includes a polarization reflection film, a waveplate, a half-mirror film, and a zoomable module. The zoomable module includes a first conductive light-transmitting substrate, a second conductive light-transmitting substrate, and a third conductive light-transmitting substrate. The third conductive light-transmitting substrate is arranged between the first conductive light-transmitting substrate and the second conductive light-transmitting substrate. The first conductive light-transmitting substrate is adhered to the waveplate with an optical-grade transparent adhesive. The polarization reflection film is directly arranged on the second conductive light-transmitting substrate. There is no substrate between the first conductive light-transmitting substrate and the third conductive light-transmitting substrate, and there is no substrate between the second conductive light-transmitting substrate and the third conductive light-transmitting substrate.
