Electronic device

An electronic device comprising:

• a substrate including:
• a display region including light-emitting regions;
• and
• a non-light-emitting region disposed between the light-emitting regions;
• an intervening insulating layer disposed on the substrate;
• a pixel unit disposed on the substrate and including:
• light-emitting elements each including:
• a first electrode and a second electrode overlapping a light-emitting region of the light-emitting regions and disposed on the intervening insulating layer;
• and
• a common layer disposed between the first electrode and the second electrode;
• pixel-defining patterns which are disposed on the intervening insulating layer;
• and
• a partition wall overlapping the non-light-emitting region and disposed between the pixel-defining patterns next to each other on the intervening insulating layer, the partition wall including:
• a first layer disposed on the intervening insulating layer;
• a second layer disposed on the first layer;
• and
• a third layer disposed on the second layer,
• wherein an opening which corresponds to the light-emitting region and exposes at least a portion of the first electrode is defined in each of the pixel-defining patterns,
• a groove, in which at least a portion of the intervening insulating layer is recessed in a direction from an upper surface to a lower surface of the intervening insulating layer, is defined in the intervening insulating layer in a recessed region which is defined between one of the pixel-defining patterns and the partition wall, and
• the common layer and the second electrode extend from the light-emitting region to the recessed region and contact the first layer.
