Display device including wire grid polarization layer

An electronic device comprising:

• a display layer comprising:
• a lower substrate,
• a pixel-circuit layer comprising a pixel circuit disposed on the lower substrate, and
• a light emitting element electrically connected to the pixel circuit;
• a quantum-dot layer disposed on the display layer and comprising a color conversion layer and a scattering layer;
• and
• an upper layer disposed on the quantum-dot layer, the upper layer comprising:
• an optical layer,
• a color filter layer on the optical layer and partially overlapping the optical layer in a direction orthogonal to a thickness direction of the display device,
• a phase retardation layer on the color filter layer,
• a wire grid polarization layer on the phase retardation layer, and
• an upper substrate directly on the wire grid polarization layer,
• wherein the color filter layer comprises a color filter overlapping with the light emitting element in the thickness direction, and
• wherein the color filter and the optical layer are in direct contact with each other.

A display device comprising:

• a display layer that emits light;
• a wire grid polarization layer disposed on the display layer and comprising wire grid pattern layers;
• and
• an upper substrate disposed on the wire grid polarization layer and forming a grid base on which the wire grid pattern layers are disposed, wherein
• the wire grid pattern layers each comprise:
• a first layer directly on the grid base,
• a second layer on the first layer, and
• a third layer on the second layer,
• the first layer and the second layer include different metal materials from each other,
• the first layer absorbs at least a portion of light incident to the first layer,
• the second layer reflects at least a portion of light incident to the second layer, and
• the third layer is an oxidation prevention layer.
