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.

Abstract: In a three-plate-type liquid crystal projector, there may be differences in the temperatures generated in each of three liquid crystal panels since the energy of light irradiated to the liquid crystal panels varies by each color. Due to the differences in the temperatures, there generates differences in the response speeds of liquid crystal molecules, which causes contours to be seen with blur tails when a moving picture is displayed. This can be overcome by the present invention in which correction amount performed on video signals supplied to three liquid crystal panels is changed by each of the three liquid crystal panels according to temperatures, when it is determined that a detected temperature has reached a prescribed value through detecting the temperature of at least one of the three liquid crystal panels, or the peripheral temperature of at least one of the three liquid crystal panels, or the temperature of a prescribed part of a liquid crystal projector.

Abstract: A liquid crystal display device comprising a first polarizing sheet (16a), a color filter layer (6) formed on glass sheet (18), a second polarizing sheet (16b), three-layered HPDLC (17) formed below the liquid crystal layer (1) and acting as a reflective structural layer having a reflectivity changed electrically, and a backlight unit as the lowermost layer. Each layer of the three-layered HPDLC (17) is composed of a liquid crystal droplet layer polymer layer and reflects blue, green, red by Bragg reflection.
