Claim Text:
1. A method of manufacturing a display panel that includes a light emitting layer separated by a partition wall, the method comprising: forming a partition wall layer above a substrate; exposing a first area of the partition wall layer using a first photomask that corresponds to a first plurality of openings; exposing a second area of the partition wall layer using a second photomask that corresponds to a second plurality of openings, the second area partially overlapping the first area; forming the partition wall by removing a part of the partition wall layer corresponding to the first plurality of openings and the second plurality of openings to form the first plurality of openings and the second plurality of openings in the partition wall layer; and forming the light emitting layer in each of the first plurality of openings and the second plurality of openings, wherein a predetermined number of openings of the first plurality of openings and the second plurality of openings form a unit constituting one pixel, the first photomask has a mask pattern in which at least one of the first plurality of openings in an overlapping area corresponds to an opening in the pixel, the overlapping area being an area where the first area and the second area overlap each other, and the second photomask has a mask pattern in which at least one of the second plurality of openings in the overlapping area corresponds to an other opening in the pixel.
