Abstract
A display device includes a substrate, a driving pad disposed on the substrate, an insulating layer covering the driving pad, disposed on the substrate, and including an engraved pattern through which at least a portion of the driving pad is exposed, and a circuit board including a circuit pad having a shape inserted into the engraved pattern and making contact with the driving pad.
Claims17
A display device comprising:
- a substrate;
- a driving pad disposed on the substrate;
- an insulating layer disposed on the substrate covering the driving pad, and including an engraved pattern through which at least a portion of the driving pad is exposed;
- and
- a circuit board including a circuit pad having a shape inserted into the engraved pattern and making contact with the driving pad,
- wherein:
- the insulating layer comprises a first insulating layer disposed on the substrate and a second insulating layer disposed on the first insulating layer;
