Abstract:
1. An antiferroelectric liquid crystal panel, having an antiferroelectric liquid crystal between a pair of substrates, which comprises a driving circuit adapted to output: a layer structure controlling voltage waveform having a frequency of 1 Hz to 100 Hz and a voltage in the range of +10 V to +50 V or −10 V to −50 V, which changes a layer structure of the antiferroelectric liquid crystal from a chevron structure to a bookshelf structure; and a display driving voltage waveform for normal display, wherein the driving circuit comprises switches which switch the output from the display driving voltage waveform to the layer structure controlling voltage waveform for an optional length of time, and wherein the switches are switched at predetermined intervals of time, or are switched in accordance with information from a temperature sensor provided with the liquid crystal panel.
