Abstract

A display device substrate which meets requirements for weight reduction, thickness reduction, high reliability, good heat resistance, and good impact resistance all at once. The display device substrate is composed of a pair of glass sheets facing each other and a layer of plastics material interposed between said paired glass sheets in such a way that said glass sheets have an internal compressive strain ascribed to the plastic sheet. Thus, the very thin glass sheets are hardly liable to breakage. This makes light weight and reduced thickness compatible with reliability.

Claims

exact text as granted — not AI-modified

What is claimed is:  
     
         1 . An improved display device substrate which is composed of a pair of glass sheets facing each other and a layer of plastics material interposed between said paired glass sheets, wherein said improvement comprises said glass sheets having an internal compressive strain.  
     
     
         2 . The display device substrate as defined in  claim 1 , wherein said glass sheets have an internal compressive strain ascribed to the layer of plastics material interposed between them.
