Display device

A display device comprising:

• a substrate;
• a transistor disposed on the substrate;
• a first electrode electrically connected to the transistor;
• a pixel defining layer disposed on the first electrode and including a pixel opening overlapping the first electrode;
• an emission layer overlapping the first electrode and disposed in the pixel opening;
• a second electrode disposed on the pixel defining layer and the emission layer;
• an encapsulation layer disposed on the second electrode;
• a first organic layer disposed on the encapsulation layer and including a rotation opening;
• and
• a second organic layer disposed inside of the rotation opening and on the first organic layer, wherein:
• the rotation opening has a planar shape formed by increasing a planar shape of the pixel opening by a ratio and rotating the planar shape of the pixel opening by an angle in a direction,
• a refractive index of the second organic layer is greater than a refractive index of the first organic layer,
• the angle, which is formed by an extension line of a side of the pixel opening and a side of the rotation opening, is about 1.5 degrees or more and about 6 degrees or less,
• a virtual opening is defined by increasing the planar shape of the pixel opening by the ratio,
• a portion of the rotation opening disposed outside of the virtual opening has a triangle shape, and
• a length of a shortest side of the triangle shape is greater than about 0 μm and less than about 1.5 μm.
