Patent ID: 7453201

Claim:
A top emission-type organic electroluminescence (EL) display apparatus comprising: a display portion comprising a plurality of organic EL elements, each organic EL element including a plurality of thin film transistors which control driving the organic EL element, a lower electrode disposed in each organic EL element, an upper electrode which is a light-transmissive common electrode shared by the plurality of the organic EL elements and extends outside the display portion, and an organic compound layer disposed between the lower electrode and the upper electrode; and an auxiliary interconnect disposed at the peripheral area of the display portion and connected to the upper electrode; and a circuit that supplies a voltage for driving the plurality of organic EL elements to the upper electrode via the auxiliary interconnect, wherein the thickness of the organic compound layer of each organic EL element is determined so that the product of the light-extraction efficiency, determined by optical interference, and the driving current of the each organic EL element, is uniform.
