1. A display device comprising:
a substrate corresponding to a first display area and a second display area;
a plurality of first pixels in the first display area;
a plurality of second pixels in the second display area, wherein a pixel density of the second display area is lower than a pixel density of the first display area;
a plurality of pixel circuits electrically connected to the plurality of first pixels and the plurality of second pixels, the plurality of pixel circuits comprising two pixel circuits located in the second display area and spaced from each other with a transmission area therebetween, each of the two pixel circuits being electrically connected to two pixel electrodes;
a first insulating layer between the two pixel circuits and the two pixel electrodes; and
a second insulating layer on the first insulating layer, the second insulating layer comprising a first portion covering an edge of each of the two pixel electrodes and a second portion adjacent to the first portion,
wherein the first insulating layer comprises:
a third portion under the first portion of the second insulating layer and each of the two pixel electrodes; and
a fourth portion under the second portion of the second insulating layer and being adjacent to the third portion,
wherein:
a height from the substrate to a top surface of the fourth portion is greater than a height from the substrate to a top surface of the third portion; and
a height from the substrate to a top surface of the second portion is greater than a height from the substrate to a top surface of the first portion.
