To reduce the difference between potentials in a circumferential part of the common electrode and in the center part, without impairing the predominance of an upper-surface luminescence type with respect to an undersurface luminescence type.
The upper surface luminescence type organic EL display apparatus is characterized, comprising an insulating substrate IS, power source lines PL1, PL2 arranged on the substrate IS; an insulating underlayer I2 which covers the substrate IS and the power source lines PL1, PL2 and is provided with a through-hole TH1 communicating with the power source line PL 2; two or more pixel electrodes PE which are arranged on the underlayer I2 and surround the through-hole TH1; an organic layer ORG which covers the pixel electrodes PE and also contains a light emitting layer, and a light transmissive common electrode CE which covers the organic layer ORG and is also connected to the power source line PL2 at the position of the through-hole TH1.
