Liquid crystal display element, methods of producing and storing the same, and electronic equipment on which the same is mounted

A liquid crystal display element comprising:

• a pair of flexible substrates sealed to one another by a sealing member, each of said substrates containing a gas barrier film and an orientating film located on sides of said substrates which oppose one another;
• a plurality of spacers disposed between said substrates, said spacers maintaining a predetermined space between said substrates;
• and
• a liquid crystal material sealed in said predetermined space between said substrates, said liquid crystal material having an oxygen saturation solubility of at least 10 .mu.l/ml;
• wherein edges of said substrates are sealed thereby providing reduced permeation of gas and water vapor into the liquid crystal material.

A method of producing a liquid crystal display element having a pair of flexible substrates sealed to each other by a sealing member with a plurality of spacers therebetween defining a predetermined space between said substrates and a liquid crystal material located in said space, each of said substrates containing a gas barrier film and an orientating film, said orientating film being in contact with said liquid crystal material, said method including the steps of:

• performing a gas barrier treatment on said substrates by sealing edges of said substrates;
• storing the sealed liquid crystal display element in a vacuum dryer under reduced pressure after performing the gas barrier treatment on said substrates;
• and
• removing the sealed liquid crystal display element from storage for assembly onto electronic equipment.
