Embodiment 1
[0071] Figure 1A , Figure 1BIt is a cross-sectional view showing the liquid crystal display device 1 according to Example 1 of the present invention. The illustrated liquid crystal display device 1 includes a light source 11, a light guide plate 12, a first light deflector 13, a second light deflector 14, a liquid crystal panel 15, a pair of stereo cameras 16a, 16b (constituting a head position detection unit and a binocular position detection unit). detection unit) and the control unit 17. The liquid crystal display device 1 of this embodiment is, for example, a flat-panel three-dimensional display capable of viewing three-dimensional images with naked eyes without wearing special glasses.
[0072] The light source 11 is composed of, for example, a plurality of light emitting diodes (Light Emitting Diodes). Figure 1A Arrange the settings in the vertical direction of the paper surface. The light source 11 radiates light toward a side surface 12 a of the light guide plate ...
Embodiment 2
[0118] Figure 5 It is a cross-sectional view showing a liquid crystal display device 1A according to Example 2 of the present invention. In addition, in each of the following examples, the same components as those of the above-mentioned example 1 are denoted by the same reference numerals, and description thereof will be omitted.
[0119] The illustrated liquid crystal display device 1A includes a polarizing reflection film 21 , a quarter-wave plate 22 , and a reflection sheet 23 in addition to the components of the liquid crystal display device 1 of the first embodiment.
[0120] The polarizing reflective film 21 is disposed between the first light deflector 13 and the second light deflector 14 . The polarizing reflective film 21 is a film having properties such that the first polarization direction (for example, with respect to Figure 5 of the paper is the light reflection in the vertical direction), and, so that the second polarization direction is orthogonal to the fir...
Embodiment 3
[0128] Figure 6 It is a cross-sectional view showing a liquid crystal display device 1B according to Example 3 of the present invention. In the liquid crystal display device 1B of this embodiment, the polarizing reflection film 21 is provided between the second light deflector 14 and the liquid crystal panel 15 . The other configurations of the liquid crystal display device 1B are the same as those of the second embodiment.
[0129] In this embodiment, the light emitted from the main surface 12 c of the light guide plate 12 passes through the first light deflector 13 and the second light deflector 14 three times. In this way, the deflection angle of the light by the first light deflector 13 can be tripled compared to the case where the light passes through the first light deflector 13 only once. In addition, compared with the case where the light passes through the second light deflector 14 only once, the deflection angle of the light by the second light deflector 14 can be...
