Patent ID: 8786820

Claim:
A display device, comprising: a substrate having a first surface, a second surface and a first side surface; a display medium layer disposed on the second surface and having a second side surface; a driving component disposed on the substrate; a flexible printed circuit (FPC) disposed on the substrate, wherein the flexible printed circuit is electrically connected to the driving component; a protective layer disposed on the display medium layer, wherein the protective layer covers the display medium layer; a backplane disposed on the first surface of the substrate, wherein a coefficient of thermal expansion (CTE) of the backplane is substantially equal to an overall coefficient of thermal expansion of a combination of the display medium layer and the protective layer; and a sealant disposed between the backplane and the protective layer, wherein the sealant surrounds the first side surface and the second side surface, and the sealant wraps at least a portion of the driving component and a portion of the flexible printed circuit.
