Abstract
Disclosed is a display device. The display device includes a gate line and a data line intersecting the gate line to define a pixel area on a substrate, a TFT formed in the pixel area and including a gate electrode, a semiconductor layer, a source electrode, and a drain electrode, a first protective layer formed on the TFT structured such that a first hole exists through the first protective layer, a second protective layer formed on the first protective layer and structured such that a second hole exists through the second protective layer, wherein the size of the second hole differs from a size of the first hole, a pixel electrode formed on the second protective layer and at least partially filling the first and second holes, the pixel electrode connected to the drain electrode through the first and second holes.
