摘要： A display apparatus includes a transparent light guide plate, a light source provided on at least one end surface of the light guide plate, and a mask provided on a front surface of the light guide plate. The light guide plate is formed of a plurality of reflecting and scattering portions having reflecting and scattering surfaces that reflect a light emitted from the light source and emit the reflected light from a front surface side. The mask allows an observer to visually recognize the light reflected from a reflective portion for the right eye, using the right eye, and the light reflected from a reflective portion for the left eye, using the left eye, whereby the reflected light beams can be stereoscopically recognized due to binocular parallax.
