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.
