1. A display device comprising:
a lower substrate;
a pixel defining layer disposed on the lower substrate and including a first opening and a second opening spaced apart from the first opening in a first direction, each of the first opening and the second opening exposing a pixel electrode in a pixel which displays a same color;
a light emitting layer disposed in each of the first opening and the second opening;
an upper substrate disposed on the light emitting layer;
a first color filter including a first surface contacting the upper substrate and a second surface opposite to the first surface in a vertical direction perpendicular to the upper substrate; and
a light blocking layer disposed on the first color filter and including a third opening partially exposing the first opening and a fourth opening partially exposing the second opening, the light blocking layer partially covering each of the first opening and the second opening in a plan view,
wherein the first color filter is disposed between the upper substrate and the light blocking layer along the vertical direction perpendicular to the upper substrate,
wherein the third opening exposes a right edge of the first opening and does not expose a left edge of the first opening in the first direction, and the fourth opening exposes a left edge of the second opening and does not expose a right edge of the second opening in the first direction in a plan view, and
wherein an entirety of a top surface of the light blocking layer directly contacts the second surface of the first color filter.
