Abstract

Disclosed is a data driving circuit comprising a digital-to-analog converter configured to supply a data voltage to a plurality of data lines connected to respective pixels and to respectively supply sensing driving data voltages having different voltage levels to the first data line and the second data line adjacent to each other among the plurality of data lines, and a line defect detecting portion connected to the first data line and the second data line and configured to sense a sensing data voltage of each of the first data line and the second data line and to detect whether a short circuit occurs between the first data line and the second data line based on the sensed sensing data voltage.
