Abstract
A display substrate includes a transistor, a black matrix and a color spacer. The transistor is connected to a gate line, and a data line crossing the gate line. The black matrix includes a first light-blocking portion covering the gate line and the data line, and a second light-blocking portion covering a channel of the transistor. The second light-blocking portion has a thickness which is smaller than a thickness of the first light-blocking portion. The color spacer is disposed on the second light-blocking portion.
