Optical device, display device, and electronic apparatus

An optical device comprising, in order:

• a beam splitter configured to transmit a portion of incident light and reflect another portion of the incident light;
• a first dimmer member configured to switch between a first mode and a second mode, the first mode causing a first transmittance for first light having a first polarization axis to be higher than a second transmittance for second light having a second polarization axis that is different from the first polarization axis, the second mode causing the first transmittance and the second transmittance to be substantially equal to each other;
• and
• a second dimmer member configured to adjust a scattering intensity of transmitted light transmitted therethrough.

An electronic apparatus comprising a display device, the display device including, in order

• an image display section configured to emit image display light having a first polarization axis,
• a beam splitter configured to transmit a portion of the image display light and reflect another portion of the image display light,
• a first dimmer member configured to switch between a first mode and a second mode, the first mode causing first light having the first polarization axis to be transmitted at a first transmittance and causing second light having a second polarization axis to be transmitted at a second transmittance that is lower than the first transmittance, the second mode causing the first light and the second light to be transmitted at a third transmittance that is higher than the first transmittance, and
• a second dimmer member configured to adjust a scattering intensity of transmitted light transmitted therethrough.
