Abstract: The present disclosure relates to an organic light emitting diode display having high luminescence. The present disclosure suggests an organic light emitting diode display comprising: a data line, a scan line and a driving current line defining a pixel area on a substrate; an anode electrode formed within the pixel area; an additional capacitance formed by overlapping expanded portions of the anode electrode with some portions of the driving current line; a bank defining a light emitting area in the anode electrode; an organic emission layer formed on the anode electrode; and a cathode electrode formed on the organic emission layer. The present disclosure suggests high luminescence organic light emitting diode display by including an additional capacitance for increasing the anode capacitance.
