Patent ID: 8237353

Claim:
A top emission type organic EL display device with a screen comprising a plurality of red pixels having an organic EL layer for emitting red color which is sandwiched between an upper electrode and a lower electrode, a plurality of green pixels having an organic EL layer for emitting green color which is sandwiched between an upper electrode and a lower electrode, and a plurality of blue pixels having an organic EL layer for emitting blue color which is sandwiched between an upper electrode and a lower electrode, wherein when total sum of current applied to the plurality of red pixels is 50 mA, total sum of current applied to the plurality of green pixels is 50 mA, and total sum of current applied to the plurality of blue pixels is 50 mA, brightness gradient is 10% or less in the screen, a film thickness of the upper electrode for the red pixel is equal to a film thickness of the upper electrode for the green pixel, and a film thickness of the upper electrode for the blue pixel is smaller than the film thicknesses of the upper electrodes for the red pixel and the green pixel.
