A light emitting display apparatus comprises a gate driver including stages connected with gate lines provided in a display area and a dummy stage connected with dummy gate lines provided in a non-display area, a sensing unit connected with the dummy stage connected with at least two dummy gate lines provided in the non-display area, and a controller connected with the sensing unit, wherein the dummy stage sequentially outputs at least two gate pulses, the sensing unit senses a voltage of a Q node to which a Q node signal for allowing the gate pulses to be output from the dummy stage is supplied, and the controller supplies a compensation signal based on the voltage to the stages.
