A display device includes a substrate having a display region and a driver
region; a gate line and a data line crossing each other to define a pixel
region in the display region, the pixel region having a pixel electrode;
an insulation layer between the gate line and the data line; a first thin
film transistor in the display region; and a second thin film transistor
having a first polarity and a third thin film transistor having a second
polarity in the driver region, wherein the pixel electrode, the gate line
and the gate electrodes of the first to third thin film transistors have
a double-layer structure in which a metal layer is formed on a
transparent conductive layer, and the transparent conductive layer of the
pixel electrode is exposed through a transmission hole passing through
the insulation layer and the metal layer in the pixel region.
