Display device

A display device comprising:

• a substrate;
• a light emitting element layer disposed on the substrate, wherein the light emitting element layer includes a first light emitting area, a second light emitting area, and a third light emitting area;
• a thin-film encapsulation layer disposed on the light emitting element layer;
• and
• a wavelength conversion layer disposed on the thin-film encapsulation layer,
• wherein the wavelength conversion layer comprises:
• a bank disposed on the thin-film encapsulation layer, overlapping the first light emitting area, wherein the bank exposes the second light emitting area and the third light emitting area;
• a reflective layer disposed on a side surface of the bank;
• a first wavelength conversion pattern overlapping the second light emitting area and a second wavelength conversion pattern overlapping the third light emitting area;
• and
• a capping layer disposed on the bank, the first wavelength conversion pattern, and the second wavelength conversion pattern,
• wherein the bank includes a first base resin and a first scatterer.

An electronic device, comprising:

• a display device which provides an image;
• and
• a processor which provides an image data signal to the display device, and
• wherein the display device comprises:
• a substrate;
• a light emitting element layer disposed on the substrate, wherein the light emitting element layer includes a first light emitting area, a second light emitting area, and a third light emitting area;
• a thin-film encapsulation layer disposed on the light emitting element layer;
• and
• a wavelength conversion layer disposed on the thin-film encapsulation layer, wherein the wavelength conversion layer comprises:
• a bank disposed on the thin-film encapsulation layer, wherein the bank exposes the first light emitting area, the second light emitting area, and the third light emitting area;
• a reflective layer disposed on a side surface of the bank;
• a light transmission pattern overlapping the first light emitting area, a first wavelength conversion pattern overlapping the second light emitting area, and a second wavelength conversion pattern overlapping the third light emitting area;
• and
• a capping layer disposed on the bank, the light transmission pattern, the first wavelength conversion pattern, and the second wavelength conversion pattern.
