ABSTRACT:
In an organic electroluminescent light emitting display device comprising a plurality of pixels each of which includes an organic electroluminescent element emitting light by a current supplied thereto, a plurality of active elements including a first active element which acquires a data signal and a second active element which regulates the current supplied to the organic electroluminescent element in accordance with the data signal, and a capacitive element storing the data signal, the present invention utilizes a part of the capacitive element arranged in one of the pixels for a light shielding member which shields the plurality of active elements arranged the one of the pixels from light emitted by the organic electroluminescent element arranged therein or another pixel adjacent thereto so as to suppress image quality deterioration and smear appearing in an image display area of the organic electroluminescent light emitting display device.
