A display panel comprising:
- a glass substrate;
- a circuit layer disposed on the glass substrate to drive a pixel;
- a light emitting element layer including a light emitting element which includes a first electrode on the circuit layer, an organic compound layer on the first electrode, and a second electrode on the organic compound layer;
- an encapsulation layer covering the circuit layer and the light emitting element layer;
- a polarizing plate on the encapsulation layer;
- and
- an organic film on the glass substrate.

A method of manufacturing a display panel from a plurality of cells disposed on a mother glass substrate having an organic film, the method comprising:
- setting a cutting line between adjacent cells of the plurality of cells;
- forming a mask on one surface of the mother glass substrate to cover regions other than the cutting line;
- etching the mother glass substrate exposed through the mask to form a first opening in the mother glass substrate;
- removing the mask;
- and
- cutting the organic film by irradiating a laser to the organic film overlapping the cutting line to separate the plurality of cells.
