1. A display apparatus, comprising:
a sampling light shielding pattern disposed on a device substrate;
an upper buffer layer disposed on the device substrate while covering the sampling light shielding pattern;
a pixel driving circuit disposed on the upper buffer layer, the pixel driving circuit including:
a driving thin film transistor including a driving gate electrode and a driving source electrode; and
a plurality of switching thin film transistors including a sampling thin film transistor electrically connected between the driving gate electrode and the driving source electrode of the driving thin film transistor; and
a light emitting device disposed on the device substrate and electrically connected to the pixel driving circuit,
wherein the sampling thin film transistor comprises a sampling gate electrode overlapping with the sampling light shielding pattern, and a sampling semiconductor pattern disposed between the sampling light shielding pattern and the sampling gate electrode, and
wherein the sampling gate electrode comprises a first electrode region extending onto a first side surface of the sampling semiconductor pattern.
