Abstract
An organic electroluminescent display apparatus including a pixel circuit and a method of driving the organic electroluminescent display apparatus are provided. Embodiments of the present invention may solve problems where the luminance of light is changed due to a change of a voltage of an anode of an organic electro-light emitting device such that an image quality is deteriorated when N-type transistors are used to form the organic electroluminescent display apparatus.
