  • 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.

  • Patent number: 11991897
    Abstract: A display apparatus includes a substrate including a first area, and a second area adjacent to the first area; first to third light-emitting diodes that are arranged in the first area and include a color emission layer; an encapsulation layer overlapping the first to third light-emitting diodes, and including an inorganic layer and an organic layer; a first light shielding wall portion disposed on the encapsulation layer, the first light shielding wall portion including a 1-1-th opening portion, a 1-2-th opening portion, and a 1-3-th opening portion corresponding to the first to third light-emitting diodes, respectively; and a second light shielding wall portion disposed on the encapsulation layer and overlapping the second area. The first light shielding wall portion and the second light shielding wall portion are spaced apart from each other in a plan view.

  • Publication number: 20230189575
    Abstract: A display apparatus includes: a first pixel electrode in a display area; a pixel defining layer with a first pixel opening defined in the pixel defining layer exposing a center of the first pixel electrode; an emission layer over the first pixel electrode and configured to emit light in a first wavelength band; an opposite electrode over the emission layer; a second substrate over the first substrate such that the opposite electrode is between the first substrate and the second substrate; a bank over a bottom surface of the second substrate in a direction to the first substrate, a first opening defined in the bank overlapping with the first pixel opening and a first additional opening defined in the bank overlapping with the peripheral area, a first quantum dot layer in the first opening; and a bonding member bonding the first substrate and the second substrate to each other.
