1. A display module comprising:
a base layer;
a circuit insulating layer disposed on the base layer and including a first portion having a first thickness, a second portion having a second thickness that is greater than the first thickness, and a third portion having a third thickness that is greater than the second thickness;
a first electrode including a first electrode portion that is disposed on the first portion of the circuit insulating layer, and a second electrode portion that extends from the first electrode portion and is disposed on the second portion of the circuit insulating layer;
an emission layer including a first light-emitting portion that is disposed on the first electrode portion of the first electrode, and a second light-emitting portion that extends from the first light-emitting portion and is disposed on the second electrode portion of the first electrode; and
an anti-reflection layer disposed on the emission layer,
wherein the anti-reflection layer comprises a partition wall having a top surface, a bottom surface opposite to the top surface, and a first inner side surface defining an opening that overlaps the first portion,
wherein the second portion includes an inclined surface,
wherein the inclined surface has a first inclination angle with respect to the base layer in the cross-sectional view,
wherein the first inner side surface has a second inclination angle with respect to the base layer in the cross-sectional view, and
wherein a sum of the first inclination angle and the second inclination angle is different from 90°.
