Data driving circuit and a display device including the same

A data driving circuit including: a latch which receives an output image signal and outputs a latch data signal including a plurality of bits; a transition detector which compares the latch data signal of a current line with the latch data signal of a previous line, and outputs a first transition detection signal based on the comparison; a delay compensator which outputs a delay data signal obtained by delaying some of the plurality of bits of the latch data signal based on the first transition detection signal; a level shifter which outputs a level shift data signal obtained by changing a voltage level of the delay data signal; and an output circuit which converts the level shift data signal into a data signal and provides the data signal obtained by converting the level shift data signal to a data line.

Display apparatus

A display apparatus includes a display panel in which pixels, signal lines connected to the pixels, and gate lines supplying gate signals to the pixels are provided, and link lines provided on a rear surface of the display panel and connected to the signal lines provided on a front surface of the display panel, wherein a test unit is provided at ends of the link lines on the rear surface.
