An organic light emitting diode (OLED) display includes a first substrate, a first electrode on the first substrate, a pixel defining layer having a first aperture exposing the first electrode, an organic light emitting layer on the first electrode, a second electrode on the organic light emitting layer, a second substrate that faces the first substrate, and a first filler and a second filler between the first and second substrates. The first filler is on the first aperture and has a higher refractive index than the second filler.
