Display device and method of fabricating the same

A method of fabricating a display device, comprising:

• providing a substrate, wherein the substrate has a first surface, a second surface and a first side surface;
• disposing a backplane on the first surface of the substrate;
• disposing a display medium layer on the second surface of the substrate, wherein the display medium layer has a second side surface;
• disposing a driving component on the substrate;
• disposing a flexible printed circuit (FPC) to the substrate, and electrically connecting the flexible printed circuit to the driving component;
• disposing a protective layer on the display medium layer, wherein the protective layer covers the display medium layer, and 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
• forming a sealant, wherein the sealant surrounds the first side surface of the substrate and the second side surface of the display medium layer, and wraps at least a portion of the driving component and a portion of the flexible printed circuit.
