Abstract:
1. A display device comprising: a display section configured to display different images intended for a plurality of different viewing ranges on the same screen, the display section including a display panel having a plurality of pixels and a parallax barrier provided on the display panel and having a plurality of apertures configured to transmit light, wherein: the plurality of different viewing ranges are determined by the relationship of the parallax barrier relative to the display panel, the viewing range of at least one of the different images displayed on the display section is not narrower than 20° but not wider than 40°, the viewing range is a range which can be observed by an observer located to the left relative to the display section or located to the right relative to the display section, the viewing range is prescribed by a crosstalk range, the plurality of different viewing ranges are set so as to satisfy equations where θm is the angle at which first first-order crosstalk begins to occur, and δd is the angle at which first second-order crosstalk begins to occur, the parallax barrier includes light-blocking, bands and light-transmitting bands in alternating fashion, the first-order crosstalk is crosstalk in which a first display image and a second display image directly overlap each other in an area centered about the angle of viewing of 90°, and the second-order crosstalk is crosstalk in which the pixel beyond the desired pixel becomes visible through another light-transmitting band of the parallax barrier, wherein θm is calculated as follows: δd is calculated as follows: where: a represents a first displacement distance by which a center of a light-transmitting band of the parallax barrier is displaced relative to an edge of a pixel for a driver's seat side, b represents a second displacement distance by which the center of the light-transmitting band of the parallax barrier is displaced relative to an edge of a pixel for a passenger's seat side, d represents an aperture width of the light-transmitting band of the parallax barrier, H represents another distance between the parallax barrier and a liquid crystal layer of the display panel, and w represents a width of each pixel of the plurality of pixels.
