Abstract:
1. A method of manufacturing a ferrodielectric liquid crystal display device, comprising: forming a lower structure body and an upper structure body each having a substrate, an electrode layer, and an orientation film; forming a cell between the lower and upper structure bodies; injecting in the cell a predetermined ferrodielectric liquid crystal in a melted state and sealing the cell; cooling to obtain phase transitions of the ferrodielectric liquid crystal corresponding to a bookshelf structure; applying a predetermined first dc potential to the electrode layers at temperatures ranging from a first temperature higher than a temperature of the phase transitions to a second temperature below a temperature of the phase transitions; stopping the application of the first dc potential and cooling to a third temperature lower than the second temperature; and applying to the electrode layers a second dc potential having a polarity opposite to the first dc potential and cooling to a fourth temperature lower than the third temperature.
