Claim 8:
9. A display device comprising:
a substrate;
a buffer layer disposed on the substrate;
a semiconductor layer of a transistor disposed on the buffer layer;
a gate insulating layer disposed on the semiconductor layer of the transistor;
a gate electrode of the transistor disposed on the semiconductor layer of the transistor;
an interlayer insulating layer disposed on the gate electrode;
an electrode of the transistor disposed on the interlayer insulating layer; and
a passivation layer disposed on the electrode of the transistor,
wherein
at least one of the buffer layer, the gate insulating layer, the interlayer insulating layer, and the passivation layer includes 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,
the first layer and the third layer include a same material,
the second layer and the fourth layer include a same material,
a pattern disposed below the first layer includes a portion that contacts the third layer, and
the first layer and the second layer do not overlap the portion of the pattern.
