1. A display device, comprising:
a substrate;
a first insulating layer disposed on the substrate and including a first surface facing the substrate and a second surface which is opposite to the first surface and flat;
a first conductive layer disposed on the substrate, the first conductive layer including a first light blocking pattern, a second light blocking pattern, and a third light blocking pattern which are separated from each other;
a second insulating layer disposed on the first conductive layer, the second insulating layer including first and second areas each including a first surface which faces the substrate and a second surface which is opposite to the first surface; and
a plurality of pixel electrodes disposed on the second insulating layer, the plurality of pixel electrodes including:
a first pixel electrode which is disposed in a first color pixel and overlaps the first light blocking pattern in a plan view, and
a second pixel electrode which is disposed in a second color pixel and covers the second light blocking pattern and the third light blocking pattern in a first direction,
wherein the first area of second insulating layer overlaps with the first pixel electrode and a second area of second insulating layer overlaps with the second pixel electrode, and
each of the second surface of the first area and the second surface of the second area of the second insulating layer includes a curved surface with a concave central portion,
wherein the second light blocking pattern and the third light blocking pattern are linear patterns extending in a second direction perpendicular to the first direction, respectively.
