摘要： The present invention provides an inexpensive projection display that allows a pixel grid as ineffective portions of respective pixels of a light valve to be made inconspicuous. The projection display includes a birefringent element (43) for spatially separating light from a transmission liquid crystal light valve (39). The birefringent element (43) includes a first birefringent plate (40) that the light from the liquid crystal light valve (39) enters, a second birefringent plate (41) that light from the first birefringent plate (40) enters, and a third birefringent plate (42) that light from the second birefringent plate (41) enters. A polarization direction of the light entering the first birefringent plate (40) forms an angle of n×45° (n is an integer other than 0) with an optic axis of the first birefringent plate (40) projected on an incident surface of the first birefringent plate (40). An optic axis of the second birefringent plate (41) projected on an incident surface of the second birefringent plate (41) is orthogonal to the optic axis of the first birefringent plate (40) projected on the incident surface of the first birefringent plate (40). An optic axis of the third birefringent plate (42) projected on an incident surface of the third birefringent plate (42) extends horizontally or vertically.

摘要： An active-matrix liquid crystal display is composed of an active matrix substrate, a liquid crystal, and an opposite substrate having a common electrode. The active matrix substrate fabricates a first group of pixel electrodes that are aligned and supplied with picture signals of a first polarity, and a second group of pixel electrodes that are aligned to adjoin with the first group of pixel electrodes respectively and are supplied with picture signals of a second polarity. An inorganic orientation film is formed on the surface of the active matrix substrate to provide a first orientation direction (Ra) to its proximal liquid crystal molecules, while an organic orientation film is formed on the surface of the opposite substrate to provide a second orientation direction (Rb), rectangularity crossing the first orientation direction, to its proximal liquid-crystal molecules.

摘要： The present invention concerns a cathode ray display tube in which the layers of a scattered electrons suppressing material are formed on the surface of a metal back layer on a phosphor layer and the inner surface of a funnel part. Each of the scattered electrons suppressing material layers on the surface of the metal back layer and on the inner surface of the funnel part is formed with an amount per unit area within specific ranges. The scattered electrons suppressing material layer is provided to form a laminated layer which is composed of lamina shaped graphite particles with a diameter which is ten times or more as large as a thickness and an average particle size in terms of spherical volume not more than 2 .mu.m. The scattered electrons suppressing material layers reduce unnecessary light emission due to scattered electrons and improve the contrast of a display image. A projection display system providing a display image with high contrast can be constituted by using the cathode display tubes.

The first and third liquid crystal panels are positioned on respective sides of the second light valve and also positioned with their image forming centers displaced relative to the associated optical axes of the first and third projection lens assemblies.

摘要： A liquid crystal image projection system projects an enlargement of an image formed in an active matrix liquid crystal panel onto a screen by using a lamp and a projector lens. The orientation of the liquid crystal panel is made such that a molecular axis vector directed from an input light side end to an output light side end of each liquid crystal molecule in the middle of the liquid crystal layer has a vector component opposite to the scanning direction of the panel, and a convergent light is entered into the liquid crystal panel. The system can solve the problem of nonuniformity of the signal voltage-transmittance characteristic of the entire screen.
