1. A light emitting display device comprising:
a substrate;
a first pixel electrode disposed on the substrate;
a pixel defining layer disposed on the first pixel electrode and including a first opening at least partially exposing the first pixel electrode;
a first light emitting layer disposed on the first pixel electrode and overlapping with the first opening of the pixel defining layer;
an insulation layer disposed on the first light emitting layer;
a black matrix disposed on the insulation layer and including a second opening overlapping with the first light emitting layer;
a second pixel electrode disposed on the same layer as the first pixel electrode:
a second light emitting layer disposed on the second pixel electrode;
a third pixel electrode disposed on the same layer as the first pixel electrode; and
a third light emitting layer disposed on the third pixel electrode,
wherein
each of the first opening of the pixel defining layer and the second opening of the black matrix has a shape with a curved portion,
the pixel defining layer further comprises a third opening at least partially exposing the second pixel electrode and overlapping the second light emitting layer,
the black matrix further comprises a fourth opening overlapping with the second light emitting layer,
the pixel defining layer further comprises a fifth opening at least partially exposing the third pixel electrode and overlapping the third light emitting layer,
the black matrix further comprises a sixth opening overlapping with the third light emitting layer, and
a shortest distance from the third opening of the pixel defining layer to the first opening of the pixel defining layer is substantially the same as a shortest distance from the third opening of the pixel defining layer to the fifth opening of the pixel defining layer.
