Abstract
A switch device includes a display device including a polarization plate including a first polarization layer that transmits a linear polarization component oscillating in a first direction, and a second polarization layer that transmits a linear polarization component oscillating in a second direction, the first and second polarization layers being stacked directly on top of one another so that the first direction is orthogonal to the second direction, a first light source unit that outputs the linear polarization component oscillating in the first direction, and a second light source unit that outputs the linear polarization component oscillating in the second direction, a switch section that performs switching between the light emitting state and the non-light emitting state of the first and second light source units, and an operating section that operates the switch section, wherein the polarization plate is provided in the operating section.
