In a liquid crystal display using liquid crystal compositions comprising cholesteric liquid crystals, a region in which the helical pitch of liquid crystal molecules is expanded and a region in which the helical pitch of liquid crystal molecules is contracted are provided on a liquid crystal cell, and are switched from one to the other by changing the electric field applied to the cell. On the other hand, it has been proposed to use liquid crystal compositions comprising cholesteric liquid crystals in LCDs. However, interference films are not generally transparent to light in the visible light region. It has been widely used as a color filter or a display medium for a color image display. For this reason, an interference film comprising liquid crystals and a dichroic dye is layered between a pair of substrates for LCs, and is used as a film for improving the contrast ratio of LCDs. Thus, it generally is not optically transparent to light in the visible light region. This type of liquid crystal layer has a large refractive index anisotropy value. A typical liquid crystal layer comprises nematic liquid crystals. A typical LCD is configured to include a liquid crystal (LC) layer sandwiched between a pair of substrates.

Liquid crystal displays (LCDs) have been widely used as display devices of electronic information appliances such as personal computers and televisions because of their advantages such as small size, light weight, and low power consumption.
