DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/111104
Kind Code:
A1
Abstract:
A display device (1) comprises: light emitting elements (5R·5G·5B) provided in respective ones of a plurality of sub-pixels (RSUB·GSUB·BSUB) and including a lower electrode (22), a hole transport layer (25), light emitting layers (8R·8G·8B), and a first upper electrode layer (28) in this order from the side of a substrate (2); and non-light emitting charge-transfer elements (6R·6G·6B) provided in respective ones of a plurality of dummy sub-pixels (DRSUB·DGSUB·SBSUB) and including the lower electrode (22), the hole transport layer (25), the light emitting layers (8R·8G·8B), and the second upper electrode layer (28a) in this order from the substrate (2) side. The non-light emitting charge-transfer elements (6R·6G·6B) comprise a resistance adjustment layer having a resistivity higher than that of the first upper electrode layer (28) and less than or equal to 1×109Ω·cm between a first surface (M1), which is a surface on the light emitting layer (8R·8G·8B) side of the hole transport layer (25), and a second surface (M2), which is a surface on the opposite side of the second upper electrode layer (28a) from the substrate (2).
