    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 device which includes a display panel that includes a first display area and a second display area, and a driving controller. During a multi-frequency mode, the driving controller drives the first display area by using a first driving frequency and drives the second display area by using a second driving frequency. During the multi-frequency mode, when the second driving frequency changes from a first frequency to a second frequency, the driving controller drives the first display area and the second display area during at least one frame by using a base frequency, drives the first display area and the second display area during at least one second frame by using an intermediate frequency between the base frequency and the second frequency, and then drives the first display area by using the first driving frequency and drives the second display area by using the second frequency.
