Abstract
A display device includes a base layer; a first pattern disposed on the base layer; an insulating layer disposed on the first pattern and including layers; and a second pattern disposed on the insulating layer. At least two of the layers of the insulating layer include a same material.
Claims16
A display device comprising:
- a base layer;
- a first pattern disposed on the base layer;
- an insulating layer disposed on the first pattern and including a plurality of layers including a first layer, a second layer directly on the first layer, a third layer directly on the second layer, and a fourth layer directly on the third layer;
- and
- a second pattern disposed on the insulating layer,
- wherein
- the first layer and the third layer include a same material,
- the second layer and the fourth layer include a same material,
- the first pattern includes a portion that contacts the third layer, and
- the first layer and the second layer do not overlap the portion of the first pattern.
