Classification: CPC G | IPC G

Claim 9:
10. A fabrication method of a display device, comprising:
forming a touch sensing layer on a base layer so that the touch sensing layer directly contacts the base layer, wherein the base layer comprises a colorless polyimide layer and a water vapor barrier layer, and the touch sensing layer comprises a second insulating layer;
disposing a light guide module on one side of the touch sensing layer, comprising:
directly disposing a cover structure on a light guide plate, wherein a material of the light guide plate comprises thermoplastic polyurethanes;
forming a dot structure on a lower surface of the light guide plate; and
forming an adhesive layer between the light guide module and the touch sensing layer such that the adhesive layer contacts and adheres the dot structure of the light guide plate and the second insulating layer of the touch sensing layer; and
disposing a display panel on the other side of the touch sensing layer and the base layer, wherein the touch sensing layer and the display panel have no adhesive material therebetween, the display panel comprises a substrate, an electronic ink layer, a lower electrode, and an upper electrode, disposing the display panel further comprises:
forming the upper electrode on a surface of the water vapor barrier layer facing away from the colorless polyimide layer such that the upper electrode contacts the surface of the water vapor barrier layer, and the upper electrode is located between the electronic ink layer and the water vapor barrier layer.
