A display device and a method of manufacturing the same are disclosed. In one embodiment, the display device includes: i) a first insulating layer formed on a first substrate, ii) a lower electrode formed on the first insulating layer, iii) a dielectric layer formed to surround the top and side of the lower electrode, wherein the dielectric layer does not cover a pixel region of the display device and iv) an upper electrode formed on the dielectric layer.

A display apparatus includes a thin film transistor having a top-gate structure and a storage capacitor that are arranged on a first substrate. An upper electrode of the storage capacitor has a size larger than a size of a lower electrode, so as to cover an entire surface of the lower electrode in a plan view. Thus, electric field caused by static electricity may be prevented from accumulating at a corner of the upper electrode when the electric filed flows from the lower electrode to the upper electrode, thereby preventing an intermediate insulating layer from being burnt.

The upper substrate includes a common electrode and an insulating member that electrically insulates the common electrode from the driving part. The insulating member has a lower dielectric constant than the liquid crystal layer. Thus, a parasitic capacitance between the driving part and the common electrode is reduced to prevent malfunction of the driving part, and a display quality is enhanced.
