Claims18
A display device, comprising:
- a substrate;
- a first electrode disposed on the substrate;
- an emission layer on the first electrode;
- a second electrode on the emission layer;
- a capacitive touch sensor disposed on the second electrode;
- and
- a conductive layer disposed on the capacitive touch sensor,
- wherein:
- the capacitive touch sensor comprises a plurality of touch electrodes having a mesh form;
- the touch electrodes comprise a first touch electrode and a second touch electrode;
