Abstract
On the display surface side of a DV display apparatus which performs image separation via a parallax barrier, a normally-white TN liquid crystal section is arranged such that a viewing angle direction heads toward the passenger seat. In a case where display is performed for both the driver's seat and the passenger seat, a drive voltage of the TN liquid crystal section is switched off. In a case where display for the driver's seat is set to non-display and an image is displayed only for the passenger seat, a halftone voltage is applied as the drive voltage of the TN liquid crystal section. In the case where display for at least one display direction is set to non-display in a display apparatus which can display different images in plural display directions by using a common display screen, it is possible to prevent image light for other directions from leaking to the non-display direction.
