Classification: CPC G | IPC G

Claim 14:
15. A fabrication method of a display device, comprising:
providing a display panel, wherein the display panel comprises a substrate, an electronic ink layer, a lower electrode, and an upper electrode;
forming a base layer covering the upper electrode of the display panel, wherein the base layer comprises a colorless polyimide layer and a water vapor barrier layer;
wherein providing the display panel 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;

forming a touch sensing layer on the base layer so that the touch sensing layer directly contacts the base layer; and
disposing a light guide module on the other side of the touch sensing layer opposite to the display panel, comprising:
directly disposing a cover structure on a light guide plate, wherein a material of the light guide plate comprises thermoplastic polyurethanes; and
forming a dot structure on a lower surface of the light guide plate;
wherein forming the touch sensing layer comprises: forming a first sensing electrode, a first insulating layer, a second sensing electrode, and a second insulating layer in sequence; 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.
