Patent ID: 7990514

Claim:
A display device comprising: a pixel region and a peripheral region over a substrate, the pixel region comprising: an active layer and a gate electrode with a gate insulating interposed therebetween: a source electrode and a drain electrode electrically connected with the active layer; a black matrix formed over the gate electrode; a pixel electrode formed over the black matrix; the peripheral region comprising: a semiconductor pattern and a first conductive pattern with the gate insulating film interposed therebetween; a second conductive pattern formed on a same layer as the source electrode and the drain electrode; a third conductive pattern formed on a same layer as the black matrix; a fourth conductive pattern formed on a same layer as the pixel electrode; and a sealing member formed over the fourth conductive pattern, wherein the second conductive pattern is wider than the first conductive pattern, and the third conductive pattern is wider than the second conductive pattern.
