Patent ID: 7880169

Claim:
A display apparatus, comprising: a gate electrode; a first insulating layer pattern formed over the gate electrode; a second insulating layer pattern formed over the first insulating layer pattern and having a gap positioned over the gate electrode, there being no second insulating layer pattern in the gap; a semiconductor film pattern formed over the second insulating layer pattern and the first insulating layer pattern; an impurity-doped semiconductor film pattern formed on the semiconductor film pattern, wherein the impurity-doped semiconductor film pattern contacts the top surface of the semiconductor film pattern and has an opening that extends to the semiconductor film pattern formed over the gate electrode; a source electrode and a drain electrode each formed over a portion of the impurity doped semiconductor film pattern; a protection film pattern formed over the source electrode and the drain electrode in a TFT area, the protection film pattern having a contact hole over the drain electrode; a pixel electrode pattern formed on the protection film pattern and electrically connected to the drain electrode.
