Display Panel and Display Device Having the Same

A display device comprising:

• a display panel including:
• a base substrate;
• a first gate line extending in a first direction on the base substrate;
• a second gate line substantially parallel with the first gate line;
• a data line extending in a second direction different from the first direction;
• a delay compensating line substantially parallel with the data line;
• and
• a delay compensating transistor electrically connected to the first and second gate lines and the delay compensating line;
• and
• a gate driving part electrically connected to first terminals of the first and second gate lines.

An apparatus for compensating gate line RC delay in a first gate line of a pair of gate lines of a display device, the apparatus comprising:

• a delay compensating line configured to provide a delay compensating voltage;
• and
• a delay compensating transistor having its control electrode coupled to a second gate line of the pair of gate lines, its input electrode coupled to the delay compensating line, and its drain electrode coupled to the first gate line,
• wherein a rising edge of a gate driving voltage applied to a second gate line is synchronized with a falling edge of a gate driving voltage applied to the first gate line, such that a falling time of the gate driving voltage applied to the first gate line is reduced when the delay compensating transistor applies the delay compensating voltage to the first gate line in response to the gate driving voltage being applied to the second gate line.
