Title:
エレクトロルミネッセンス表示装置
Document Type and Number:
Japanese Patent JP4266648
Kind Code:
B2
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.
