Title:
ELECTROLUMINESCENT ELEMENT, ELECTROLUMINESCENT ELEMENT MANUFACTURING METHOD, DISPLAY DEVICE, AND ILLUMINATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/029156
Kind Code:
A1
Abstract:
An electroluminescent element (10) is provided with an anode layer (12), a cathode layer (14) disposed opposite the anode layer (12), pillars (13) formed in the space between the anode layer (12) and the cathode layer (14), and light emission layers (17) formed at locations other than the locations where the pillars (13) are formed; and the pillars (13) are formed so that the following conditions (1) and (2) are at least 95% satisfied. With this configuration, an electroluminescent element is provided that is unlikely to suffer from emission unevenness or shorts and has high durability. (1) At least some of the pillars (13) are contained within a 10μm radius circular region the center of which is a discretionary position on the surface of the anode layer (12). (2) At least some of the emission layers (17) are contained within a 20μm radius circular region the center of which is a discretionary position on the surface of the anode layer (12).
