Organic light emitting diode display

A method for manufacturing an organic light emitting device, the method comprising:

• forming a plurality of electrodes on a first substrate;
• forming a pixel definition layer to cover the plurality of electrodes on the first substrate;
• forming a plurality of openings in the pixel definition layer to correspond to a plurality of electrodes to expose the plurality of electrodes;
• forming a spacer on the pixel definition layer;
• mounting a deposition mask having a mask opening corresponding to the opening of the pixel definition layer on the spacer;
• and
• depositing an organic emission material through the mask opening,
• wherein the pixel definition layer comprises a first opening and a second opening adjacent to each other along a first direction by an interval for each pixel, and a third opening adjacent to the first opening and the second opening by an interval along a second direction crossing the first direction,
• wherein the spacer is at a crossing point of a first imaginary line extending in the first direction and passing between the first opening and the third opening and a second imaginary line extending in the second direction and passing between the first opening and the second opening, and
• wherein an edge of the mask opening is separated from a top end of the spacer.
