Claims
- 1. A method of manufacturing a display device comprising, in the order recited, the steps of:
- providing two soda-lime glass plates having main surfaces;
- polishing at least one main surface of each of the glass plates;
- dipping each of the two glass plates in a salt solution which contains cations having an ionic radius which is larger than the ionic radius of sodium in order to strengthen the glass plates to form compression strength of approximately 100 kg/mm.sup.2 at the surface;
- forming a passivation film on the polished main surface of each of the glass plates;
- forming transparent electrodes on the passivation film on each of the glass plates; and
- assembling the two glass plates together with a gap therebetween and filling the gap with liquid crystals.
- 2. The method according to claim 1 wherein said step of dipping includes heating the salt solution.
- 3. The method according to claim 2 wherein the salt solution is a molten salt solution.
- 4. The method according to claim 1 wherein the cations which have an ionic radius larger than the ionic radius of sodium are selected from the group consisting of potassium and rubidium.
- 5. A method of manufacturing a display device, comprising the steps of:
- providing two soda-lime glass plates;
- forming at least one transparent electrode on a surface of each of the glass plates;
- assembly and pasting the two glass plates together with the surfaces which carry the electrodes facing one another to form a cell; and
- dipping the cell in a salt solution which contains cations having an ionic radius which is larger than the ionic radius of sodium in order to strengthen the glass plates.
- 6. The method according to claim 5 wherein said step of dipping includes heating the salt solution.
- 7. The method according to claim 6 wherein the salt solution is a molten salt solution.
- 8. The method according to claim 5 wherein the cations which have an ionic radius larger than the ionic radius of sodium are selected from the group consisting of potassium and rubidium.
- 9. The method according to claim 5 wherein said step of assembling and pasting is performed so that a gap exists between the glass plates, and further comprising, after said step of assembling and pasting, the step of filling the gap between the glass plates with liquid crystals.
- 10. The method according to claim 9 wherein said step of dipping includes heating the salt solution.
- 11. The method according to claim 10 wherein the salt solution is a molten salt solution.
- 12. The method according to claim 9 wherein the cations which have an ionic radius larger than the ionic radius of sodium are selected from the group consisting of potassium and rubidium.
