Organic electroluminescence display panel and organic electroluminescence display apparatus

摘要

An organic electroluminescence (EL) display panel includes a cathode electrode formed above a bank and formed opposite to a plurality of anode electrodes, and a charge functional layer commonly formed for each of the organic light-emitting layers across a plurality of aperture areas formed in the bank. A distance from the center of the display region to the end of the cathode electrode is shorter than a distance from the center of the display region to the end of the charge functional layer.
