Abstract: The invention provides a thin reflective plate having cholesteric liquid crystal that can prevent or reduce a decrease of reflection efficiency. A reflective plate includes a cholesteric liquid crystal layer, and the cholesteric liquid crystal layer includes a plurality of regions in which the helical axes of the cholesteric liquid crystal are aligned in different directions in the plane of a substrate, and therefore, the regions can reflect color light components having different wavelengths. Consequently, the cholesteric liquid crystal layer can reflect light formed of light components of different colors (for example, white light) as a whole. When the reflective plate is applied to a reflective liquid crystal display device or the like, it is possible to appropriately reflect white light for display.

Abstract: A phase-invariant layer, which is formed at areas that are not transmission areas, forces light entering the reflection areas of a transflective LCD from a backlight unit to move into transmission areas by reflection, so that the amount of light used in a transmission mode is increased. In this way, light utilization efficiency and display luminance of the LCD are improved.

Abstract: The present invention is related to a method of method of manufacture of a reflective polarizing film that can improve brightness of a liquid crystal display device remarkably by making a liquid crystal film that can cover visible light by using cholesteric liquid crystal layers having different selective light-reflection central wavelengths, attaching a quarter wave (¼ λ) retardation film on top of the liquid crystal film, and adding prism patterns to the opposite side of the liquid crystal film. The reflective polarizing film of the present invention is characterized by that two or more cholesteric liquid crystal layers having different selective reflection wavelength regions are laminated in order from a shorter wavelength to a longer wavelength, and brightness of a liquid crystal display device is maximized owing to an integrated film manufactured by attaching a ¼ λ retardation film onto cholesteric liquid crystal layers and forming prism patterns onto the opposite side.

Abstract: A liquid crystal switchable color filter switches between three color bands and is preferably used for time-sequential devices, such as projection devices, direct view displays and video cameras. The color filter may employ circularly polarizing selective reflection bands of at least four cholesteric filters together with three liquid crystal switches and related retarder layers. In one embodiment, the handedness of the second cholesteric is equal to the handedness of the third cholesteric filter and opposite to the handedness of the first and fourth cholesteric filter and, for the blocking state of a color band, the optic axis of the corresponding liquid crystal switch is parallel or perpendicular to the polarization direction. This concept leads to improved, excellent color saturation and requires less stringent production tolerances than in the prior art. Moreover, it advantageously allows overlapping color transmission bands thus improving the light efficiency.
