Title: Liquid-crystal shutter

Abstract: A pair of transparent film substrates are provided. A transparent electrodeand an orientation film are formed on each of the pair of transparent filmsubstrates in sequence. A liquid crystal is inserted between the pair offilm substrates. An orientation process is performed on each of theorientation films such that a visual-angle direction in which a maximumcontrast is obtained is a six-o'clock direction or a twelve-o'clockdirection based on a direction of the short hand of a clock. Each of thepair of film substrates is an optically anisotropic body, having aretardation value in the range of 5 to 30 nm in the plane of the filmsubstrates. Assuming that long-axis directions denote directions parallelto the longest side of the periphery of the liquid-crystal shutter, thelagging-axis directions in the plane of the film substrates areapproximately parallel to the long-axis directions.
