    Abstract: Provided is a scan driver of a display device, and the scan driver includes a driving circuit and a masking circuit. The driving circuit includes a control circuit, a first output circuit, and a second output circuit. The control circuit outputs a first control signal and a second control signal. The first output circuit is connected to a first output terminal which outputs a first scan signal and a first voltage terminal and operates in response to a first control signal. The second output circuit is connected to a first output terminal and a second voltage terminal and operates in response to a second control signal. The masking circuit outputs a second scan signal to a second output terminal in response to the first control signal and the second control signal and is connected to an input terminal to which a masking signal is supplied.

    Abstract: A display apparatus is disclosed that comprises a display panel. The display panel includes a display region that includes a first display area and a second display area. A data driver is configured to provide a data voltage to the display region. A gate driver is configured to provide a compensation gate signal and an initialization gate signal to the display region. The gate driver includes a first stage and a second stage. A driving controller is configured to control the gate driver and the data driver. The driving controller is configured to determine a first driving frequency for the first display area and a second driving frequency for the second display area. The second stage is configured to provide the compensation gate signal having a pulse duration shorter than a pulse duration of the compensation gate signal provided to the display region by the first stage.

    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.
