摘要:
A screen has a screen main body, a power supply and a voltage regulator. The screen main body has a Fresnel lens, a polymer dispersed liquid crystal unit and a lenticular lens. The liquid crystal unit includes a polymer dispersed liquid crystal and a pair of transparent electrodes which sandwich the polymer dispersed liquid crystal. By operating the voltage regulator, a voltage applied to the electrodes is adjusted so that a gain of the liquid crystal is controlled.

A side light type backlight having a light source including a plurality of LEDs, and a light guide plate. Opposing end surfaces of the light guide plate are light incidence surfaces at which the plurality of LEDs are arranged. Wherein a plurality of rows of the LEDs are arranged in a direction of a thickness of the light guide plate. Under a first option, each row of LEDs is arranged in a longitudinal direction of the light incidence surface of the light guide plate, and electrically connected to one another in series. Under a second option, each row of LEDs is arranged in a longitudinal direction of the light incidence surface of the light guide plate, with N number of the LEDs being electrically connected in series in which the LEDs adjacent to each other belong to different rows.

To suppress a decrease in the contrast caused by the reflection on the interface to the air layer without decreasing the quality of display. A reflection-type liquid crystal display device includes a light guide plate having a polarizing element stuck or adhered thereto on the side facing a reflection-type liquid crystal display panel and arranged maintaining a predetermined gap relative to the reflection-type liquid crystal display panel. The display device further includes a source of light arranged on an end surface side of the light guide plate, and a member having a light-diffusing function and interposed between the polarizing element and the light guide plate.

A projection-type display apparatus includes a light source, a liquid crystal panel, and a light path changing element arranged between the light source and the liquid crystal panel for changing a light path so that a light beam emitted by the light source and going to the central portion of the liquid crystal panel is bent toward the peripheral portion of the liquid crystal panel. Therefore, a uniform illuminance distribution and a uniform color distribution are ensured.

A projection display apparatus includes a light source unit for emitting light, a modulation unit for spatially modulating the light from the light source unit, and a projection lens for projecting light spatially modulated by the modulation unit on a screen so that a picture corresponding to spatial modulation in the modulation unit is formed on the screen. A deflection unit is located between the light source and the modulation unit and deflecting beams are included in the light from the light source unit toward an optical axis to prevent the beams from traveling out of the modulation unit.

A backlight device including a light guide plate having an upper surface configured to face a liquid crystal panel, a lower surface, and at least one side surface extending in a thickness direction between the upper surface and the lower surface. The backlight device also includes a plurality of LEDs for irradiating light beams to the side surface of the light guide plate, which side surface serves as a light incidence surface. The plurality of LEDs are arranged in a plurality of rows in the thickness direction of the same side surface of the light guide plate so as to extend in a longitudinal direction of the light incidence surface. Additionally, of the plurality of LEDs, two LEDs that are electrically connected to each other in series are disposed in different rows.
