Abstract: A microlouver has, as a basic unit, a light-controlling layer in which a light-absorbing layer and a transparent layer are laminated together, and a plurality of basic units L and S comprising a plurality of types of light-controlling layers having different layer thicknesses or optical constants, disposed in the direction of the layer thickness of the basic units. The array mode of the basic units L and S is determined based on a random number or a sequence-generating rule. For this reason, the microlouver has a large number of frequency components in terms of spatial frequency, and moire fringes that have a specific period and are normally caused by the interference with other optical elements are therefore prevented from occurring.

A light-direction controller is disposed on one side of the optical fibers, main fibers is disposed above and below the light-direction controller, and a main fiber is disposed at the other end of the row of fibers. Light sources are connected to each of the end portions of the main fibers. Three types of mirrors that mutually differ in direction are formed on the surface of the light-direction controller, light emitted from a main fiber enters the optical fibers by way of a first mirror, and light emitted from a main fiber enters the optical fibers by way of a second mirror.

Abstract: A microlouver includes a periodic structure in which a transparent layer and a light absorption layer are alternately disposed with a constant, repetitive period. The range of the exit direction of a light beam passing through the transparent layer is restricted by the light absorption layer. The periodic structure includes a periodic structure portion divided in the direction that intersects the direction in which the transparent layer and the light absorption layer are repeatedly disposed. In the periodic structure portion, between the periodic structures adjacent to each other, there is a difference of 180 degree in the phase of spatial frequency of each periodic structure.

Abstract: A display device is composed of a light source device and a transmissive liquid crystal display panel, and the light source device is provided with a transparent/scattering switching element capable of switching between states in which incident light is transmitted or scattered. Pixels for displaying are disposed in the form of a matrix in the transmissive liquid crystal display panel, and the need for another power supply and signals for the transparent/scattering switching element is eliminated by driving the transparent/scattering switching element using the signals and power supply for driving the pixels. The drive power source of the transparent/scattering switching element for controlling scattering can be made smaller and less costly in a display device that is capable of switching the range of viewing angles.

Abstract: The display device is divided into a low scattering region and a high scattering region. The display device is disposed on a backlight, thereby constituting a display unit with the display device and the backlight. The low scattering region and the high scattering region can be driven separately from each other. That is, it is a structure in which at least a part of the region in the display device has a scattering power that is different from that of the other region, and each region can be driven independently.
