  • Patent number: 8557333
    Abstract: The invention is directed to an electroluminescent display device in which a first planarization insulating film need not be used so that a manufacturing cost reduces, and a display defect caused by a cut in an organic EL layer or moisture absorption at a step portion is prevented. An R color filter layer, a G color filter layer, and a B color filter layer are so formed that end portions of the adjacent R, G, and B color filter layers overlap each other. The R color filter layer, the G color filter layer, and the B color filter layer serve as a first planarization insulating film. For planarization, the end portions of the color filter layers overlap each other. For reducing a step height of an overlapping portion, the end portions of the color filters are formed in a tapered shape.

  • Publication number: 20120112234
    Abstract: Each pixel includes a region where a lower reflection film is not present. In each pixel, there is a region where a microcavity structure is formed between a counter electrode and a lower reflection film and another region where the microcavity structure is not formed. The regions differentiated in cavity length can differently enhance the peak wavelength so as to improve the viewing angle dependence. Furthermore, in each of R, G, and B light emitting pixels, the area ratio of a region where the microcavity structure is present and another region where the microcavity structure is not present can be adjusted so as to eliminate the differences caused by the microcavity structure.
