Abstract
A thin film transistor array substrate and a method for manufacturing the same are disclosed. The thin film transistor array substrate includes a plurality of pixel units defined by a cross structure of gate lines with data lines and power lines on a substrate. Each of the pixel units includes a driving unit, which includes a switching thin film transistor and a driving thin film transistor receiving a signal from the gate line, the data line, and the power line, and a capacitor storing a signal; and a light emitting unit emitting light on a pixel electrode receiving a driving current from the driving thin film transistor. Each of a plurality of shielding patterns is positioned under the switching thin film transistor and the driving thin film transistor of the pixel unit.
