[0098] [Construction of TV broadcasting signal transmitter / receiver system]

[0099] figure 1 is a block diagram showing a configuration example of a transmitter / receiver system including the receiver side unit 200 and using the television broadcast signal 100A according to the first embodiment of the present invention. The transmitter / receiver system includes a transmitter side unit 100 for transmitting a television broadcast signal 100A, for example, by wired communication such as cable TV or wireless communication such as terrestrial digital wave or satellite wave; and a receiver side unit 200, For receiving the television broadcast signal 100A from the receiver side unit 200 through the above-mentioned wired or wireless communication. It should be noted that the receiver-side unit 200 corresponds to a specific example of "display device" in the present invention.

[0100] The television broadcast signal 100A includes image data for two-dimensional display (planar display...

[0240] Next, the receiver side unit 200 according to the second embodiment of the present invention will be described below. like Figure 47 As shown, the receiver-side unit 200 according to this embodiment differs from the receiver-side unit 200 according to the above-described embodiments in that a light modulation device 60 is used instead of the light modulation device 30 . Differences from the configurations of the above-described embodiments will be mainly described, and points in common with the configurations of the above-described embodiments will not be further described.

[0241] In the light modulation device 60, a vertical alignment film is used as the alignment films 33 and 35, such as Figure 48 As shown, a light modulating layer 64 is included in place of the light modulating layer 34 .

[0242] In the case of using a vertical alignment film as the alignment films 33 and 35 , in bulk material 64A and microparticles 64B to be described later, a pretilt oriente...

Abstract

The invention discloses a display and an illumination unit. A light modulation layer disposed between a first transparent substrate and a second transparent substrate generates a plurality of first strip-like illumination light beams extending in a direction intersecting with a first end surface of the first or second transparent substrate at a first angle with use of light from a light source, when an electric field for a first mode is applied from an electrode to the light modulation layer. The light modulation layer generates a plurality of second strip-like illumination light beams extending in a direction intersecting with the first end surface at an angle different from the first angle or a direction parallel to the first end surface with use of light from the light source, when an electric field for a second mode is applied from the electrode to the light modulation layer.

Description

technical field [0001] The present invention relates to a display device capable of performing two-dimensional display (planar display) and three-dimensional display (stereoscopic display), and an illumination unit suitably applied to such a display device as a backlight. Background technique [0002] Display devices capable of performing three-dimensional display include display devices that require wearing special glasses for three-dimensional display and display devices that do not require special glasses. In the latter display device, for example, a lenticular lens or a parallax barrier is used to perceive a stereoscopic image with naked eyes. When image information is distributed in the right and left eyes through a lenticular lens or a parallax barrier, the right and left eyes see different images, respectively, and as a result, three-dimensional display can be realized. [0003] However, in the case of using the above-mentioned parallax barrier, the resolution at the...
