Disclosed herein is a display device, including: a substrate; a circuit part configured to include a drive element formed over the substrate; a planarization insulating layer configured to be formed on the circuit part; an electrically-conductive layer configured to be formed on the planarization insulating layer and include a plurality of first electrodes and an auxiliary interconnect; an aperture-defining insulating layer configured to insulate the plurality of first electrodes from each other and have an aperture through which part of the first electrode is exposed; a plurality of light emitting elements configured to be formed by stacking the first electrode, an organic layer including a light emitting layer, and a second electrode in that order; and a separator configured to be formed by removing the planarization insulating layer at a position surrounding a display area in which the plurality of light emitting elements connected to the drive element are disposed.
Description
[0001] References to related applications [0002] The present application contains subject matter disclosed in Japanese Priority Patent Application JP 2009-243589 filed in the Japan Patent Office on Oct. 22, 2009, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention relates to a display device and a method for manufacturing the display device. More specifically, the present invention relates to a method of manufacturing a self-luminous display device using an organic electroluminescence (EL) element. Background technique [0004] In recent years, organic EL displays using organic EL elements have been attracting attention as display devices replacing liquid crystal displays. An organic EL display is a self-luminous display in which an organic material emits light by itself in response to application of a current to the organic material. The organic EL display has excellent characteristics such as no need for a bac...
