Display apparatus and method of manufacturing the same

A display apparatus comprising a first display area and a second display area comprising a transmission area, the display apparatus comprising:

• a substrate;
• an insulating layer on the substrate;
• a semiconductor layer on the insulating layer;
• a first light-emitting element and a second light-emitting element that are arranged in the second display area on the substrate and apart from each other with the transmission area between the first light-emitting element and the second light-emitting element;
• and
• a lower metal layer disposed between the insulating layer and the substrate in the second display,
• wherein the lower metal layer comprises a first surface facing the substrate and a second surface opposite to the first surface, and the first surface of the lower metal layer comprises uneven portions.
