Abstract: A REFLECTION TYPE LIQUID CRYSTAL PROJECTOR IS PROVIDED WHICH INCLUDES LIQUID CRYSAL DISPLAY PANELS (5R, 5G AND 5B) TO MODULATE COLOR RAYS OF LIGHT (R, G AND B) CORRESPONDING TO THREE PRIMARY COLORS (RED, GREEN AND BLUE), RESPECTIVELY, ON THE BASIS OF VIDEO DATA AND A SYNTHESIZING PRISM (6) TO SYNTHESIZE THE COLOR RAYS OF LIGHT (R, G AND B) MODULATED BY THE LIQUID CRYSTAL DISPLAY PANELS (5R, 5G AND 5B) INTO ONE IMAGE. THE LIQUID CRYSTAL DISPLAY PANEL (5G) WHICH PROVIDES AN IMAGE INVERTED IN RELATION TO THOSE PROVIDED BY THE LIQUID CRYSTAL DISPLAY PANELS (5R AND 5B) IS ALIGNED IN A DIRECTION (X2) DIFFERENT FROM THOSE (X1) IN WHICH THE LIQUID CRYSTAL DISPLAY PANELS (5R AND 5B) ARE ALIGNED, SO THAT THE ALIGNMENT DIRECTIONS (X1 AND X2) OF THE LIQUID CRYSTAL DISPLAY PANELS (5R, 5G AND 5B) WILL BE COINCIDENT WITH EACH OTHER IN AN IMAGE DISPLAYED ON A SCREEN (S). THUS, COLOR STAINING CAN BE PREVENTED FROM TAKING PLACE ON THE IMAGE RESULTED FROM SYNTHESIS OF THE COLOR RAYS OF LIGHT MODULATED BY THE LIQUID CRYSTAL DISPLAY PANELS (5R, 5G AND 5B).

Abstract: A battery effect causing asymmetry in liquid crystal responses can be prevented, an offset voltage applied to a driving voltage can be reduced, and high reliability is secured even during long term driving. A pixel electrode is covered with a metal film (43) which has a standard electrode potential with a sign opposite to that of a metallic material constituting the pixel electrode. This prevents the battery effect between the opposing electrodes, unlike conventional devices which do not have the metal film (43). Thereby, the asymmetry in the liquid crystal responses can be prevented and reducing the offset voltage which is required for the driving voltage can be accomplished unlike the conventional ones. Moreover, a circuit for applying the offset voltage is simplified or unnecessary, and improvement of long term reliability during the driving can be accomplished.

Abstract: In a reflective liquid crystal display device according to the invention, burn-in in a long-term drive which occurs due to asymmetric structures of side surfaces of an inter-pixel groove can be prevented, and long-term drive reliability can be achieved. A first obliquely evaporated alignment film (43A) is formed on a first side surface of the inter-pixel groove in a sectional surface of a pixel electrode substrate (41) in a thickness direction through evaporation, and a second obliquely evaporated alignment film (43B) is formed on a second side surface facing the first side surface through evaporation. Thereby, the film structures of both side surfaces of the inter-pixel groove in the sectional surface become symmetric, so burn-in in a long-term drive which occurs due to the asymmetric structures of the side surfaces of the inter-pixel groove can be prevented.

Abstract: A white fluorescent material contains Y2O2S as a matrix and activators of Tb and Eu both having a concentration within the range of 0.05 to 0.3 mol %. The white fluorescent material exhibits neither colour shading nor uneven light emission and is readily dispersible. The white fluorescent material can, for example, be used in a fluorescent surface of a kinescope used in a system for recording images on colour photographic film.

Abstract: A magnetic head comprising a magnetic path (1) and a vertically magnetizable film (3). The magnetic path contains a first gap (G1) facing a magnetic recording medium (5) and a second gap (G2). The vertically magnetizable film (3) is formed across the second gap (G2) on the principal plane or outer circumference of the magnetic path (1). A linearly polarized light beam is irradiated onto the vertically magnetizable film and the resulting reversal of magnetization in the vertically magnetizable film is detected through the use of a polar Kerr effect. This scheme allows data to be reproduced with sufficient sensitivity from tracks of very small widths.
