Patent ID: 8040444

Claim:
A display device comprising: a storage electrode pattern on a substrate; a first dielectric layer on the storage electrode pattern; a drain electrode on the first dielectric layer; a second dielectric layer on the first dielectric layer, the second dielectric layer having a first contact hole through which a portion of the drain electrode is exposed; an insulating layer on the second dielectric layer, the insulating layer having a second contact hole corresponding to the first contact hole and a third contact hole through which a portion of the second dielectric layer over the storage electrode pattern is exposed; and a pixel electrode electrically connected to the drain electrode, the pixel electrode comprising a storage electrode portion in the third contact hole over the storage electrode pattern, wherein the storage electrode pattern, the first dielectric layer, the second dielectric layer and the storage electrode portion of the pixel electrode overlap to form a storage capacitor and the first dielectric layer covers an entire portion of the storage electrode pattern, wherein a portion of the first dielectric layer formed on the storage electrode pattern directly makes contact with the second dielectric layer.
