摘要： A display panel is disclosed that includes a substrate, a first light blocking line, a second light blocking line, and a third light blocking line located on the substrate. The first, second, and third light blocking lines extend in a first direction in a plan view, and are spaced apart from one another in a second direction that intersects the first direction. A first display element and a second display element are located between the first light blocking line and the second light blocking line and respectively emit light of a first color and light of a second color. A third display element is located between the second light blocking line and the third light blocking line and emits light of a third color.
