Organic el device, method of manufacturing the same, and organic el display

An organic EL display comprising:

• a display part having a plurality of organic EL devices arranged therein, each organic EL device comprising a pair of electrodes disposed so as to oppose each other and a luminescent layer, disposed between the electrodes, containing a polymer having an anthracene structure and a hole-transferring compound having a glass transition temperature of at least 70° C.;
• a power supply part, electrically connected to each of the pair of electrodes, for supplying a voltage or current to the electrodes;
• and
• a switching part for turning on/off the organic EL devices.

An organic EL device comprising:

• a hole injection electrode and an electron injection electrode disposed so as to oppose each other;
• a luminescent layer, disposed between the hole injection electrode and electron injection electrode, containing a polymer having an anthracene structure and a modified part, disposed near a surface on the side closer to the electron injection electrode, containing a hole-blocking compound having a bandgap of at least 4.0 eV;
• and
• an electron-blocking layer, disposed between the hole injection electrode and luminescent layer, containing a hole-transferring compound having an electron affinity of 3.0 eV or less.
