Abstract
A display substrate includes a pixel switching element, a pixel electrode, a reference line, a control switching element, a bias line, a light sensing element, a sensing capacitor and a light blocking filter pattern. The pixel switching element is connected to a data line and a gate line, includes a first semiconductor pattern. The pixel electrode is connected to the pixel switching element. The reference line is in parallel with the data line. The control switching element is connected to the reference line and the gate line, includes a second semiconductor pattern. The bias line is in parallel with the gate line. The light sensing element is connected to the bias line and the control switching element, includes a third semiconductor pattern. The sensing capacitor is connected to the light sensing element and a storage line. The light blocking filter pattern transmits a first light, and blocks a second light.
