Abstract: A display substrate includes a base substrate, a gate electrode, a semiconductor layer, a source electrode, a drain electrode, a first black organic layer, a data line and a pixel electrode. The gate electrode is disposed on the base substrate. The semiconductor layer is disposed on the gate electrode. The source electrode is disposed on the semiconductor layer. The drain electrode is disposed on the semiconductor layer and is spaced apart from the source electrode. The first black organic layer is disposed on the source electrode and the drain electrode. The data line is disposed on the first black organic layer, and is electrically connected to the source electrode through a contact hole formed through the first black organic layer. The pixel electrode is electrically connected to the drain electrode. Thus, display quality of a display apparatus including the display substrate may be improved.

Abstract: A display substrate includes a base substrate, a gate metal pattern, a semiconductor layer, and a data metal pattern. The base substrate includes a display area and a peripheral area. The gate metal pattern includes a gate electrode of a transistor and includes a gate metal member disposed on the peripheral area. The transistor is disposed on the display area. The semiconductor layer includes a channel portion of the transistor and includes a semiconductor member disposed on the peripheral area. The data metal pattern includes a source electrode of the transistor and includes a data metal member disposed on the peripheral area, electrically connected to the gate metal member, and directly contacting the semiconductor member. A maximum thickness of the data metal member in a direction perpendicular to the base substrate is greater than a maximum thickness of the semiconductor member in the direction.

Abstract: A substrate peeling apparatus includes a support member and absorption pads. The support member, having a quadrangular shape, includes first and second vertexes diagonally facing each other in a first direction, and third and fourth vertexes diagonally facing each other in a second direction crossing the first direction. The absorption pads is disposed on the support member. The absorption pads are arranged in rows in a direction parallel to the first direction and at least one absorption pad of each row is arranged in a direction parallel to the second direction. An absorption pad of each row includes a hole having an increasing internal diameter as a distance in the first direction between the each row and the first vertex increases. An internal diameter of an absorption pad in a row positioned halfway between the first and second vertexes has a maximum internal diameter.
