摘要： An optical diode which can lower the cost and save electric power is provided. An optical diode 21 of the present invention comprises a cholesteric liquid crystal (CLC) layer 2 having a selective reflection wavelength band with a left-handed helical structure, and a phase shifter 24 for changing the phase difference between two intrinsic polarized light components of left-handed circularly polarized light having a wavelength within the selective reflection wavelength band of the CLC layer 2. When left-handed circularly polarized light having a wavelength within the selective reflection wavelength band of the CLC layer 2 is incident on the phase shifter 24 in the optical diode 21, for example, the phase shifter 24 turns the left-handed circularly polarized light into right-handed circularly polarized light, this right-handed circularly polarized light can be transmitted through the CLC layer 2. When left-handed circularly polarized light having a wavelength within the selective reflection wavelength band of the CLC layer 2 is incident on the CLC layer 2, on the other hand, this left-handed circularly polarized light is selectively reflected by the CLC layer 2. Thus, an optical diode characteristic is realized. This optical diode 21 does not require a large amount of time and labor to manufacture. Further, since no nonlinear optical effect is utilized, it is not necessary for laser light having such a high intensity as to cause the nonlinear optical effect to be incident as incident light.

摘要： A liquid crystal display device having improved and broadened viewing angle characteristics. The device includes a liquid crystal cell of the twisted nematic type for driving sandwiched by a pair of upper and lower polarizing plates in which at least one compensating film is inserted between the liquid crystal cell and the upper polarizing plate or between the liquid crystal cell and the lower polarizing plate. Alternatively, two compensating films are respectively inserted between the liquid crystal cell and the upper polarizing plate and between the liquid crystal cell and the lower polarizing plate. The compensating film consists essentially of a liquid crystalline polymer showing optically a positive uniaxiality, the liquid crystalline polymer being fixed in a nematic hybrid orientational order. The device is further characterized by an angle between a tilt direction of the compensating film and a pretilt direction on a liquid crystal cell substrate opposed to a substrate for the liquid crystal cell for driving closest to the compensating film in the range of 165.degree. and 195.degree.
