Organic electroluminescent light emitting display device
View Patent ↗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.
1. An organic electroluminescent light emitting display device, comprising:
a substrate having a principal surface;
a plurality of pixels arranged two-dimensionally on the principal surface of the substrate;
a plurality of scanning signal lines juxtaposed along a first direction on the principal surface of the substrate:
a plurality of data signal lines juxtaposed along a second direction transverse to the first direction on the principal surface of the substrate; and
a plurality of current supply lines arranged on the principal surface of the substrate;
wherein each of the plurality of pixels has a plurality of active elements, a plurality of capacitive elements storing a data signal transmitted by one of the plurality of data signal lines, and an organic electroluminescent element emitting light by a current which is supplied to organic electroluminescent element from one of the plurality of current supply lines, and
a part of at least one of the capacitive elements is arranged in such a manner that overlaps to the data signal line, extends along the data signal line in a plan view from the principal surface of the substrate and located between the active element and a light emitting region of the organic electroluminescent element.
2. An organic electroluminescent light emitting display device according to claim 1 ,
wherein a part of at least one of the capacitive elements is arranged in such a manner that overlaps to the current supply line and extends along the current supply line in a plan view from the principal surface of the substrate.
3. An organic electroluminescent light emitting display device according to claim 1 ,
wherein a part of at least one of the capacitive elements is arranged in the vicinity of a light emitting region of the organic electroluminescent element in a plan view from the principal surface of the substrate.
4. An organic electroluminescent light emitting display device according to claim 1 ,
wherein each of the plurality of pixels is divided into a first region where the plurality of active elements are formed and a second region where the data signal line and the current supply line are formed along the principle surface of the substrate.
5. An organic electroluminescent light emitting display device according to claim 4 ,
wherein a part of at least one of the capacitive elements is arranged in a rest part of the first region and the second region in a plan view from the principal surface of the substrate.
