Abstract

In a display apparatus, a light sensor of a display includes a light sensing layer, a source electrode, a drain electrode, an insulating layer, and a gate electrode to sense light from an external source. The light sensing layer is disposed on the substrate to sense light, and the source and drain electrodes are disposed on the light sensing layer and are covered by the insulating layer. The gate electrode is disposed on the insulating layer. An edge of the gate electrode is disposed on the light sensing layer at least in an area where the light sensing layer is overlapped with the source and drain electrodes.
