ELECTROLUMINESCENT ELEMENT, ELECTROLUMINESCENT ELEMENT MANUFACTURING METHOD, DISPLAY DEVICE, AND ILLUMINATION DEVICE |
摘要 |
An electroluminescent element (10) is provided with: an anode layer (12), a cathode layer (14) arranged to face the anode layer (12), pillars (13) formed in the space between the anode layer (12) and the cathode layer (14), and a light emitting layer (17) formed at a location 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 short circuit and has high durability. (1) At least a part of the pillars (13) is included within a 10-µm diameter circular region the center of which is an arbitrary position on the surface of the anode layer (12). (2) At least a part of the light emitting layer (17) is included within a 20-µm diameter circular region the center of which is an arbitrary position on the surface of the anode layer (12). |
