Title:
ORGANIC EL DISPLAY DEVICE, AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/090931
Kind Code:
A1
Abstract:
An organic EL display device (1) having an anode (3) and a cathode (4), and also having a blue organic EL element (10B), a green organic EL element (10G) and a red organic EL element (10R). The blue organic EL element (10B) has a first light-emitting layer (51), the green organic EL element (10G) has a second light-emitting layer (52), and the red organic EL element (10R) has a third light-emitting layer (53). The organic EL elements (10B, 10G, 10R) have a fourth light-emitting layer (54) as a shared layer. The fourth light-emitting layer (54) is directly connected to each of the light-emitting layers (51, 52, 53). The first light-emitting layer (51) contains a chemical compound that is represented by general formula (1) and has at least one group represented by a general formula (11), and the fourth light-emitting layer (54) contains a second chemical compound represented by a general formula (2).
