1. A display apparatus comprising:
a first planarization layer comprising a first via hole and a second via hole;
a first subpixel comprising a first pixel electrode and a first pixel definition layer,
wherein the first pixel electrode is arranged on the first planarization layer, and is electrically connected to a first pixel circuit through the first via hole, and
wherein the first pixel definition layer is arranged on and exposes a first area of the first pixel electrode;
a second subpixel comprising a second pixel electrode and a second pixel definition layer,
wherein the second pixel electrode is arranged on the first planarization layer, and is electrically connected to a second pixel circuit through the second via hole, and
wherein the second pixel definition layer is arranged on and exposes a second area of the second pixel electrode, the second area being smaller than the first area;
a first light blocking layer comprising a first opening overlapping the first pixel electrode;
a second light blocking layer comprising a second opening overlapping the second pixel electrode;
a first color filter overlapping the first opening; and
a second color filter overlapping the second opening,
wherein a second distance defined as a shortest distance from an inner surface of the second opening to the second via hole is greater than a first distance defined as a shortest distance from an inner surface of the first opening to the first via hole.
