MULTICOLOR ORGANIC EL ELEMENT ARRAY

摘要

PROBLEM TO BE SOLVED: To provide a multicolor organic EL element array which suppresses deterioration in durability characteristic while reducing cost. SOLUTION: The multicolor organic EL element array includes: a positive electrode and a negative electrode; an organic light-emitting layer sandwiched between the positive electrode and negative electrode and colored in a plurality of colors by pixels; and a common electron transport layer formed over the plurality of pixels. The EL element array is characterized in that a voltage adjusting layer is provided closer to the negative electrode than the organic light-emitting layer of a pixel having the lowest driving voltage.
