PROBLEM TO BE SOLVED: To provide an organic EL element array having low power consumption and having red, green, and blue light-emitting elements. SOLUTION: In an organic EL element array, the light-emitting layer of any light-emitting element satisfies the formula, 1/10<μe/μh<10 (μe represents the electron mobility of the light-emitting layer andμh represents hole mobility).
