  • Publication number: 20250081790
    Abstract: A display device includes a display panel including a circuit element layer and a light emitting element layer on the circuit element layer, and a first light conversion layer, a second light conversion layer, and a light transmitting layer on the display panel and spaced apart from one another. The light emitting element layer includes a pixel defining layer that defines light emitting openings that overlap the first light conversion layer, the second light conversion layer, and the light transmitting layer, a plurality of light emitting elements arranged in the light emitting openings, respectively, and a barrier wall on the pixel defining layer, the barrier wall being black in color. When viewed from above, the barrier wall is located between light emitting elements adjacent to each other among the plurality of light emitting elements and extends parallel to sides of the adjacent light emitting elements that face each other.
