Abstract
Provided are a display substrate and a display device including the same. The display substrate includes: gate wiring; a first semiconductor pattern formed on the gate wiring and having a first energy bandgap; a second semiconductor pattern formed on the first semiconductor pattern and having a second energy bandgap which is greater than the first energy bandgap; data wiring formed on the first semiconductor pattern; and a pixel electrode electrically connected to the data wiring. Because the second energy bandgap is larger than the first energy bandgap, a quantum well is formed in the first semiconductor pattern, enhancing electron mobility therein.
