    摘要: An OLED device comprises a cathode, a light emitting layer and an anode, in that order, wherein (i) the light-emitting layer comprises up to 10 volume % of a light emitting compound and at least one anthracene host compound of Formula (3): wherein W1-W10 independently represents hydrogen or an independently selected substituent, and (ii) a further layer located between the cathode and the light emitting layer, contains (a) 10-volume % or more of an anthracene compound of Formula (3) and (b) at least one salt or complex of an element selected from Group IA, IIA, IIIA and IIB of the Periodic Table. Such devices exhibit reduced drive voltage while maintaining good luminance.
