ABSTRACT:
The invention provides an electroluminescent display device in which purity of R, G, and B colors is prevented from lowering by minimizing white light leakage and color mixture caused by an escape of light to an outside of a color filter layer. An organic EL element driving TFT is formed on an insulating substrate. A first planarization insulating film is formed so as to cover the organic EL element driving TFT. A color filter layer is buried in the first planarization insulating film. An anode layer is connected with the organic EL element driving TFT and extends over the first planarization insulating film. A second planarization insulating film is formed so as to cover end portions of the anode layer. Here, a length of an overlapping area of the color filter layer and the second planarization insulating film is set larger than a sum of thicknesses of the anode layer and the first planarization insulating film. Accordingly, most of light radiated from an organic EL layer can be transmitted through the color filter layer103.
