Abstract
A display device may include the following elements: a substrate; a light blocking layer disposed on the substrate; a first insulating layer disposed on the light blocking layer; a transistor including a source or drain electrode having an extension that overlaps each of the first insulating layer and the light blocking layer; a second insulating layer disposed on the extension; and a pixel electrode disposed on the second insulating layer. The first insulating layer and the second insulating layer may include a contact hole that exposes a portion of the light blocking layer and exposes a portion of the extension. The pixel electrode may directly contact each of the portion of the extension and the portion of the light blocking layer.

A display device comprising:
- a substrate;
- a gate line disposed on the substrate;
- a first insulating layer disposed on the gate line;
- a data line disposed on the first insulating layer, wherein an edge of the data line is perpendicular to an edge of the gate line;
- a transistor comprising a source or drain electrode, wherein the source or drain electrode comprises an extension that overlaps the first insulating layer;
- a second insulating layer overlapping each of the data line and the extension and including a contact hole that exposes a portion of the extension;
- and
- a pixel electrode directly contacting the portion of the extension,
- wherein, in a plan view of the display device, the contact hole has a straight side that is oriented at an angle relative to the edge of the data line, and wherein the angle is in a range of 15 degrees to 75 degrees.
