Disclosed is a plasma addressed liquid crystal display improved to prevent deterioration of liquid crystal and an alignment film due to ultraviolet rays generated by plasma discharge. The plasma addressed liquid crystal display includes a liquid crystal cell including columns of signal electrodes, a plasma cell including rows of discharge channels, and an intermediate thin glass sheet through which the liquid crystal cell is joined to the plasma cell. The thin glass sheet includes an ultraviolet ray transmission preventive layer having a function of absorbing or reflecting ultraviolet rays generated in the discharge channels on the plasma cell side thereby preventing the ultraviolet rays from being made incident on the liquid crystal cell side.

In a liquid crystal display apparatus including a liquid crystal layer sandwiched by a front glass substrate and a back glass substrate, spacers contained in the liquid crystal layer to maintain a predetermined thickness of the liquid crystal layer are made from a conductive material. This enables to reduce flicker and baking generated by electric charge caused by impurities ions remaining on the boundary surface of the liquid crystal layer.

The generation of crosstalk is suppressed when displaying a three-dimensional image, and a decrease in brightness is avoided when displaying a two-dimensional image.A polarization control filter 268 is placed so that a boundary between a polarization region 269a and a polarization region 269b is within the ranges of a red liquid crystal cell 272, a green liquid crystal cell 274, and a blue liquid crystal cell 276 in order in the vertical direction. When displaying a three-dimensional image, black is displayed for a liquid crystal cell 2 positioned at a boundary between the polarization region 269a and the polarization region 269b of a polarization control filter 268, and the original right eye image or left eye image is displayed by other liquid crystal cells.

A LCD display includes a light source section, a LCD panel including a plurality of pixels each having sub-pixels of R, G, B, and Z, and a display control section including an output signal generation section. The display control section performs a display drive on the sub-pixels with use of the respective output video signals, and performs a lighting drive on the light source section with use of the lighting signal. The output signal generation section generates output video signals corresponding to the respective four colors, based on the input video signals, and generates a lighting signal of the light source section, based on the input video signals, to perform a predetermined dimming processing, based on both the input video signals and the generated lighting signal, and finally generates the output video signals through performing a predetermined color conversion processing, based on a resultant video signal from the dimming processing.

Disclosed is a transmissive liquid crystal projector carrying a vertical alignment liquid crystal device. The liquid crystal projector includes a liquid crystal panel (25), on the light incident side and on the light radiating side of which a light incident side polarizing plate (24) and a light radiating side light polarizing plate (26) are arranged, respectively. A first polarized light component in a light beam collected by an illuminating optical system is transmitted through the light incident side polarizing plate (24) and routed to the liquid crystal panel (25). An optical anisotropic device (45), tilted by a preset angle correlated with the direction of alignment of liquid crystal molecules in the liquid crystal panel (25), that is, a pre-tilt angle, is arranged between the light incident side polarizing plate (24) and the liquid crystal panel (25) or between the light radiating side light polarizing plate (26) and the liquid crystal panel (25). By so doing, a high contrast ratio may be maintained, while transmittance of the liquid crystal panel may be improved.
