Abstract: A display apparatus includes a base substrate layer, a circuit layer, a light-emitting element layer, and an encapsulation layer. The base substrate layer includes a display area. The circuit layer is on the base substrate layer and includes at least one transistor. The light-emitting element layer is connected to the circuit layer and includes at least one light-emitting element in the display area. The at least one light-emitting element has an exiting surface emitting light and a step shape. The encapsulation layer is on the light-emitting element layer.

Abstract: A display apparatus includes a plurality of pixels for receiving a plurality of gate signals, and a plurality of data voltages, a level shifter for receiving a gate driving voltage and a plurality of gate control clocks to generate a plurality of reference clocks, and for generating a plurality of control clocks by delaying the reference clocks by a predetermined time, a gate driver for outputting the gate signals in response to the control clocks, a short circuit protector for sensing a current of each control clock at each falling edge of each gate control clock to detect a static current of the each control clock, and for outputting a shut-down signal based on a count of the static current detection, and a voltage generator for providing the gate driving voltage to the level shifter, and shutting down in response to the shut-down signal.
