Title:
ORGANIC EL DISPLAY PANEL AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2013/099276
Kind Code:
A1
Abstract:
The present invention provides an organic EL display panel and a method for manufacturing the same, which comprise an organic light-emitting layer formed by ink-jet method and can effectively minimize the degradation of image display due to the generation of streaking. Specifically, in the process of forming a bank layer, the arrangement locations of each opening (13) which is aligned along a column (Y) direction are mutually displaced between the opening group in a first column and the opening group in a second column. In the process of forming the organic light-emitting layer, a head section (301) is scanned along a row (X) direction and nozzles (3030) used for the first column and the second column are switched. Thereby, if nozzles having an error in jet volume are switched, this prevents organic light-emitting layers (9) having the same error in film thickness from being successively formed in the row (X) direction. Thus, brightness inconsistency that may occur on an organic EL display panel (100) can be prevented.
