Abstract

A display substrate includes a base substrate, a data line, a gate line, a switching element, a self assembled monolayer (SAM) and a pixel electrode. The data line is formed on the base substrate. The gate line is formed across the data line. The switching element includes a source electrode electrically connected to the data line, a drain electrode spaced apart from the source electrode, a semiconductor pattern covering the source and drain electrodes, and a gate electrode electrically connected to the gate line and facing the semiconductor pattern. The SAM is disposed around the semiconductor pattern and a conductive pattern including the data line. The pixel electrode is electrically connected to the switching element.

Claims (24)

1. A display substrate comprising:

a base substrate;

a conductive pattern comprising a data line formed on the base substrate and extending along a first direction;

a gate line disposed on the base substrate and extending along a second direction crossing the first direction;

a switching element comprising:
