Display panel and display device having the same

A display panel comprising:

• an electrostatic discharge (ESD) protection circuit area at a side of a peripheral area surrounding a display area comprising a plurality of pixels, the ESD protection circuit area comprising a plurality of ESD protection circuits;
• a fan-out area at another side of the peripheral area, comprising a plurality of fan-out lines configured to receive data signals and to transmit the data signals to a corresponding plurality of data lines extending lengthwise in a second direction, and a pad configured to receive a global signal;
• a common line area between the ESD protection circuit area and the fan-out area, comprising:
• a first common line extending lengthwise in a first direction crossing the second direction;
• a plurality of switching elements each connected to a corresponding one of the data lines;
• a second common line extending lengthwise in the first direction and configured to transmit the global signal to the switching elements to concurrently control the switching elements;
• and
• a plurality of global signal lines connecting lengthwise in the second direction from the first common line to the second common line to transmit the global signal to the second common line;
• and
• a transmission line connecting lengthwise from the pad to the first common line to transmit the global signal to the first common line,
• wherein a width of the transmission line is greater than a width of the global signal lines and a width of the data lines.

A display device comprising:

• a display panel having a display area comprising a plurality of pixels, and a peripheral area surrounding the display area;
• a scan driver configured to provide scan signals to the pixels;
• a data driver configured to provide data signals to the pixels;
• a control line driver configured to provide a global signal to the pixels;
• and
• a controller configured to control the scan driver, the data driver, and the control line driver,
• wherein the peripheral area comprises:
• an electrostatic discharge (ESD) protection circuit area at a side of the peripheral area and comprising a plurality of ESD protection circuits;
• a fan-out area at another side of the peripheral area, comprising a plurality of fan-out lines configured to receive the data signals and a pad configured to receive the global signal;
• a common line area between the ESD protection circuit area and the fan-out area, comprising a common line extending lengthwise in a pixel row direction;
• a transmission line connecting lengthwise from the pad to the common line to transmit the global signal to the common line;
• and
• a plurality of global signal lines extending lengthwise in a pixel column direction from the common line and through the ESD protection circuit area to the display area to concurrently transmit the global signal to the pixels, and
• wherein a width of the transmission line is greater than a width of the global signal line.
