Provided is a display device.The display device includes: a substrate; a light blocking pattern disposed on the substrate; a semiconductor pattern disposed on the light blocking pattern; a gate insulating layer disposed on the semiconductor pattern; a gate wiring; an interlayer insulating layer formed on the gate wiring; a first contact hole for exposing the source area; a data wiring disposed to extend in the second direction on the interlayer insulating layer and electrically connected to the source area via the first contact hole; a first passivation layer disposed on the data wiring; a second contact hole, which is disposed between the neighboring protrusion portions of the light blocking pattern so as not to overlap the light blocking pattern, and exposes the drain area; and a pixel electrode disposed on the first passivation layer and electrically connected to the drain area through the second contact hole.
