Abstract: A display panel includes an upper display substrate and a lower display substrate. The upper display substrate includes a base substrate, a light shielding pattern, and including an opening part defined therein which corresponds to the pixel region, a color filter overlapped with the pixel region, an encapsulation layer disposed in lower sides of the light shielding pattern and the color filter, a partition wall disposed in a lower side of the encapsulation layer, overlapped with the light shielding region, and including a partition wall opening part defined therein which corresponds to the pixel region, and a quantum dot layer disposed inside the partition wall opening part. The partition wall includes a first layer directly disposed on the bottom surface of the encapsulation layer and a second layer directly disposed on a lower side of the first layer and having a larger optical density than the first layer.

Abstract: A display apparatus is provided including a first substrate on which a plurality of organic light-emitting diodes are arranged. A second substrate is bonded to the first substrate. The second substrate includes a plurality of light control units respectively corresponding to the plurality of organic light-emitting diodes and a plurality of banks arranged between the plurality of light control units. The plurality of banks include a first bank having a deflection arrangement structure in which a fluorine-containing polymer is concentrated on a surface of a side of the first bank, and a second bank that does not have a deflection arrangement structure in which the fluorine-containing polymer is deflectively arranged.

Abstract: The display panel includes an upper display substrate including a plurality of pixel areas and a light blocking area, a lower display substrate. The upper display substrate includes a base substrate, a barrier part overlapping the light blocking area and disposed on the base substrate, a light blocking layer including a first light blocking portion disposed on the barrier part and a second light blocking portion disposed on the same layer as the barrier part to respectively overlap the pixel areas, a reflection layer including a first reflection portion disposed on the first light blocking portion and a second reflection portion disposed on the second light blocking portion, and a light control layer overlapping the pixel areas and disposed on the reflection layer. A plurality of openings passing through the second light blocking portion and the second reflection portion are defined in each of the pixel areas.
