Patent ID: 7061174

Claim:
An electroluminescent display device comprising: a plurality of pixels disposed on an insulating substrate; a color filter layer provided in each of the pixels and formed above the insulating substrate; an anode layer disposed above each of the color filter layers; a first planarization insulating film interposed between the color filter layers and the anode layers; a second planarization insulating film disposed above the first planarization insulating film and extending over the anode layers so as to cover end portions of the anode layers; an electroluminescent layer disposed above each of the anode layers; and a cathode layer disposed above the electroluminescent layers, wherein each of the color filter layers is confined to an area of a corresponding pixel and overlaps with the second planarization insulating film by a length that is larger than a sum of a thickness of the anode layer and a thickness of the first planarization insulating film located above the color filter layers.
