Display device

A display device comprising:

• a base;
• a first insulating layer disposed on the base;
• a first lower electrode and a second lower electrode, disposed on the first insulating layer;
• a second insulating layer disposed on the first insulating layer and including a first aperture which overlaps the first lower electrode, a second aperture which overlaps the second lower electrode, and a first trench located between the first aperture and the second aperture;
• an organic layer which covers the second insulating layer, the first lower electrode located in the first aperture and the second lower electrode located in the second aperture, and including a light emitting layer;
• and
• an upper electrode which covers the organic layer, wherein
• the first trench comprises:
• a first trench portion including a bottom surface and a first side surface and a second side surface rising from the bottom surface;
• a second trench portion located above the first trench portion and including a first bottom portion extending from the first side surface to an outer side of the first trench, a second bottom portion extending from the second side surface to an outer side of the first trench, a third side surface rising from the first bottom portion, and a fourth side surface rising from the second bottom portion;
• and
• a third trench portion located above the second trench portion and including a third bottom portion extending from the third side surface to an outer side of the first trench, a fourth bottom portion extending from the fourth side surface to an outer side of the first trench, a fifth side surface rising from the third bottom portion, and a sixth side surface rising from the fourth bottom portion,
• a first gap between the first side surface and the second side surface in a lower portion of the first trench portion is greater than a second gap between the first side surface and the second side surface in an upper portion of the first trench portion,
• a third gap between the third side surface and the fourth side surface in a lower portion of the second trench portion is greater than a fourth gap between the third side surface and the fourth side surface in an upper portion of the second trench portion,
• a fifth gap between the fifth side surface and the sixth side surface in a lower portion of the third trench portion is greater than a sixth gap between the fifth side surface and the sixth side surface in an upper portion of the third trench portion,
• the third gap is greater than the first gap and less than the fifth gap, and
• the fourth gap is greater than the second gap and less than the sixth gap.
