Abstract: In a display device in which a display material is enclosed in a gap between bonded glass substrates and in a method of manufacturing the same, in order to use a conventional method of scratching the surfaces of the glass substrates to divide them into cells, sodium atoms on the surface of the glass substrate having a thickness of not larger than 2 mm are replaced with atoms having an ion radius larger than that of sodium to form a chemically reinforced layer having a thickness of not larger than 20 &mgr;m. According to this display device and this method of manufacturing the same, the strength of a flat display device used in a portable electric equipment can be easily improved.

Abstract: A display device comprises a pair of opposed soda-lime glass substrates. A chemically reinforced layer having a thickness of 20 &mgr;m or less is disposed on the surface of at least one of the opposing soda-lime glass substrates. An electrode is disposed on opposed surfaces of the soda-lime glass substrates, and a display material is disposed between the pair of opposing soda-lime glass substrates.
