1. A display device comprising:
a substrate including a display area and a non-display area;
a light-emitting element layer in the display area of the substrate;
a color conversion layer facing the light-emitting element layer and including a bank in the display area of the substrate and extending from the display area and into the non-display area of the substrate;
a capping layer in the display area and the non-display area of the substrate and covering the bank;
a plurality of color filters in the display area and in the non-display area of the substrate, wherein the plurality of color filters in the non-display area overlap each other; and
in order from the plurality of color filters, in a direction away from the substrate:
an overcoat layer in the display area and the non-display area of the substrate and respectively covering the plurality of color filters; and
an optically-functional layer in the display area and the non-display area of the substrate and facing the overcoat layer,
wherein in the non-display area:
each of the substrate, the capping layer, each of the plurality of color filters, and the overcoat layer has a lateral side which is furthest from the display area, and
the lateral side of the substrate, the lateral side of the capping layer, the lateral side of each of the plurality of color filters, and the lateral side of the overcoat layer are coplanar with one another.
 
15. A display device comprising:
a substrate including a display area and a non-display area;
a light-emitting element layer in the display area of the substrate;
a color conversion layer facing the light-emitting element layer and including a bank in the display area of the substrate and extending from the display area and into the non-display area of the substrate;
a capping layer in the display area and the non-display area of the substrate and covering the bank;
a plurality of color filters in the display area and in the non-display area of the substrate, wherein the plurality of color filters in the non-display area overlap each other; and
in order from the plurality of color filters, in a direction away from the substrate
a first overcoat layer in the display area and the non-display area of the substrate and respectively covering the plurality of color filters; and
an optically-functional layer in the display area and the non-display area of the substrate and facing the first overcoat layer,
wherein within the non-display area:
each of the substrate, the capping layer, each of the plurality of color filters, and the first overcoat layer has a lateral side which is furthest from the display area,
the lateral side of the substrate, the lateral side of the capping layer, the lateral side of each of the plurality of color filters, and the lateral side of the first overcoat layer are coplanar with one another,
the first overcoat layer has a top face which is furthest from the substrate and respectively at a vertical level relative to the substrate in the non-display area and in the display area, and
the vertical level of the top face of the first overcoat layer which is in the non-display area is equal to the vertical level of the top face of the first overcoat layer which is in the display area.
