Abstract
The disclosure provides a driving thin film transistor and a switching thin film transistor each using an oxide semiconductor pattern as an active layer thereof. The driving thin film transistor and the switching thin film transistor include light shielding patterns, respectively. Each light shielding pattern includes a semiconductor material layer doped with P-type impurity ions. By virtue of the light shielding patterns including the semiconductor material layer, the driving thin film transistor and the switching thin film transistor achieve an increase in threshold voltage, thereby securing freedom of design.
