Abstract
A method of fabricating a display substrate is provided. The method includes forming a conductive layer on a base substrate; and performing a chemical vapor deposition process to form an oxide layer on a side of an exposed surface of the conductive layer away from the base substrate, the exposed surface of the conductive layer including copper, the oxide layer formed to include an oxide of a target element M. The chemical vapor deposition process is performed using a mixture of a first reaction gas including oxygen and a second reaction gas including the target element M, at a reaction temperature in a range of 200 Celsius degrees to 280 Celsius degrees. A mole ratio of oxygen element to the target element M in the mixture of the first reaction gas and the second reaction gas is in a range of 40:1 to 60:1.
