pixel electrodes disposed on the substrate facing the openings;

organic light-emitting layers disposed in the openings, electrically connected to the pixel electrodes; and

an opposite electrode disposed on the light-emitting layers,

the width of the openings corresponding to the first edge sub-pixel line is less than the width of the openings corresponding to the center sub-pixel lines that emit the same color of light, and

the width of the openings corresponding to the second edge sub-pixel line is less than the width of the openings corresponding to the center sub-pixel lines that emit the same color of light.
