Title:
FLAT IMAGE DISPLAY
Document Type and Number:
WIPO Patent Application WO/1999/034393
Kind Code:
A1
Abstract:
A plurality of fixing bases (32) are arranged on the inner side of a back case (10). An electrode unit (11) which includes a back electrode substrate (33) serving as a back electrode and a plurality of electrode plates is disposed on the fixing bases (32). The electrode plates are laid on the back electrode substrate and they are unitized. Out of the fixing bases (32), only the fixing bases at generally the central portion of the back electrode substrate (33) are secured to the back electrode substrate (33). The other fixing bases are provided with substrate holding springs (36) so as to fix the back electrode substrate (33) by the elastic forces. Thanks to such a fixing structure, the influence of the heat strain caused during the production process and during the driving, and the influence of external vibration and shock are absorbed and eliminated, thus providing a flat image display of high precision and high image quality.
